Do orcas reproduce asexually or sexually
In nature, social factors influence the reproduction of male orcas, as they cannot mate until they achieve size and strength enough to compete with other individuals of their species. Females can become ready for mating several times a year, so there is no regular pattern in the reproductive aspect of killer whales Orcas use sexual reproduction. Females are pregnant for approximately 17 months before birth. We can never be sure, but scientists say that female Orcas don't fell pain during reproduction process. They give birth every 3-10 years The first phase a male whale goes through when it attempts to find a female mating partner to reproduce with is to attract a female whale during a courtship phase No males are known to exist. The lizards (from the genus Aspidoscelis) reproduce via parthenogenesis, a process in which eggs develop into embryos without first being fertilized They produce both sexually and asexually it depends on the species.they produce asexually and sexually.when reproducing asexually, they use binary fission.when reproducing sexually, they use..
Adult killer whales give birth to a single baby (only once were twins recorded) about every 3-10 years. They start breeding at about 14-15 years of age (the youngest known was only 11). Gestation is 16-17 months. Babies nurse for about one year Most fish reproduce sexually (as per usual there are exceptions). Marine dwelling mammals (dolphins and whales) all reproduce sexually. Do whales reproduce in captivity? They cant keep Whales in..
While most snakes reproduce sexually, some reproduce asexually. It depends on the species. When snakes reproduce sexually, the male snake inserts his hemipenes into the female's cloaca to fertilize the eggs. If you are curious about snake reproduction, there is a lot to learn As pointed out by others, viruses don't really reproduce so much as convince cells to make copies of them, which could be considered a form of asexual reproduction if you wanted to classify it that way. However, certain viruses can also perform wh.. All fish reproduce sexually through a process called spawning. Like all sexual reproduction, it involves the union of sperm from a male fertilizing the egg of a female. Though the entire reproductive process is sexual, many times the fertilization of the eggs of the female take place outside of the body rather than internally as happens with. In 99% of iguana reproduction, it occurs sexually. Iguanas are one of the few lizards that can reproduce through a process called parthenogenesis. This is a form of asexual reproduction where a female can impregnate herself. A big adaptation is the desire to seek out heat. If its cold, it will hunt for a warm spot
. Snakes are one of the few species that are capable of both types of reproduction. Although asexual reproduction is not common across all species of snakes, it does occur in some, and that too, when the mating conditions are unfavorable Do whales reproduce sexually or asexually? Most marine and estuarine animals reproduce sexually — including oysters, sharks and whales. To make things even more confusing, some animals like moon jellies reproduce sexually during one stage of life and asexually during another Asexual reproduction requires only one parent and produces offspring that are genetically identical to the parent.

Asexual reproduction is a method of reproduction in which the organism is basically making clones of itself. This method of reproduction differs from sexual reproduction as it does not require gametes (sperm and egg) from the opposite sexes. In bacteria, fungi and plants, asexual reproduction is very common and is usually used along with sexual reproduction as a method to further greatly the.
Killer Whale Reproduction - Killer Whale Facts and Informatio
When unisexual and bisexual species of the same genus are reared under similar conditions in the laboratory, the population of the unisexual species grows more quickly because all unisexual lizards (all females) deposit eggs, whereas only 50% of the bisexual lizards do so (Figure 7-4).

Why are most organisms sexual? The question of why most species reproduce sexually and others reproduce asexually has stymied biologists for years (particularly since asexual reproduction has many advantages including producing more offspring.) The question is answered in part in this week's Science Magazine, published on Friday, October 19
Reproduction - The Details on Killer Whale
- Asexual reproduction is the primary way in which bacteria reproduce. The main difference between asexual and sexual ways of reproduction is that the former one produces mostly genetically identical individuals. Plants that develop from a successful asexual reproduction usually grow much faster and reach the adult plant stage sooner
- Both have their disadvantages and advantages within an environment. While the majority of the animal kingdom reproduces sexually, many reproduce asexually—and some organisms have the ability to perform both ways! Sexual reproduction. Sexual reproduction is the combination of genetic material from 2 different sexes
- It is a known fact that the advanced and most evolved class of animal kingdom - the homo sapiens reproduce sexually. But there are cases where humans reproduce through asexual modes. Asexual reproduction in humans is carried out without the immediate use of fertilization of the male and female sex cells (the sperm and egg)
- Etymology and definitions. The word whale comes from the Old English hwæl, from Proto-Germanic *hwalaz, from Proto Indo European *(s)kwal-o-, meaning large sea fish. The Proto-Germanic *hwalaz is also the source of Old Saxon hwal, Old Norse hvalr, hvalfiskr, Swedish val, Middle Dutch wal, walvisc, Dutch walvis, Old High German wal, and German Wal. The obsolete whalefish has a similar.
- Most snakes reproduce sexually, but some reproduce asexually. They mate in the spring after hibernation, using pheromones to attract mates. A male snake mates with a female snake by inserting one of his hemipenes into the female's cloaca. This fertilizes the eggs inside her oviduct. A month after, she lays her eggs, which hatch two months later
- Flowering plants can reproduce both by sexual and asexual means of reproduction. Sexual reproduction involves the fusion of male and female gametes which takes place through pollination by birds, insects, and water. This pollination causes the fertilization and the female ovules grow into seeds. Asexual reproduction can take place naturally as well as artificially. The natural vegetative.
How Do Whales Reproduce? Whale Fact
Whale Reproduction Whales are mammals and are nourished in the womb through an umbilical cord. Whales even have a belly button after birth (this is the place where the umbilical cord was attached to). Whales are viviparous, they give birth to live young (unlike fish, most of which lay eggs) All animals can reproduce sexually, but some can do both ways. Colonial animals such as siphonophores, corals, and bryozoans are particularly good at asexual reproduction, but like everything else they can reproduce sexually. However, asexual reproduction is known in some lizards, some molluscs, many parasites, and some other animals, too Sexual Reproduction . Blue whales reproduce via sexual meiosis. The male and female each produce haploid gametes. Male gametes are sperm, and the female gametes are eggs. A single sperm and egg fertilize to form a diploid zygote. They fertilize internally, meaning sperm is deposited inside the female 206 MHR • Unit 2 Reproduction Sexual Reproduction In section 6.1, you learned how male and female gametes are formed and how meiosis produces gametes that are not genetically identical. Sexual reproduction is the process that brings these non-identical gametes together to form a new organism. Sexual reproduction has three stages This type of reproduction is very different from other aquatic animals such as fish and amphibians as they are known to lay eggs that hatch (usually externally), meaning that the bond between child and mother is much less significant and unlike dolphins fish and amphibians do not feed or nurture their child through an umbilical cord
All-Female Lizard Species Reproduce Without Male
- Depending on the species of Octopus, mating can occur from a couple of months of age or when they are several years old. Depending on the type of species there may be some courting and ritual going on before the actual mating occurs. With most of the species though it is more a matter of convenience than anything else
- Start studying Biology - B13. Learn vocabulary, terms, and more with flashcards, games, and other study tools
- LESSON 9 SEXUAL REPRODUCTION IN FLOWERING PLANTS Asexual reproduction has advantages and dis-advantages. On the one hand, it is convenient because it requires only one parent. The quali-ty of an organism that results from asexual reproduction will remain more or less the same. For example, if a plant has fruit or flow
- Whatever the case, the lives of both male and female mosquitoes revolve around mating, so just how do the buzzing insects do it? Across the globe there are more than 3,000 species of mosquitoes
- Once born, sharks grow slowly. Sexual maturity is reached at between 15 and 20 years of age in most species. This is another reason that it is vital that, by the time the pups are actually born, they are strong and developed enough to defend themselves and their population numbers
5. Hydra can reproduce asexually, by budding, or sexually. When food is plentiful, many Hydra reproduce asexually by producing buds in the body wall, which grow to be miniature adults and break away when they are mature. When conditions are harsh, often before winter or in poor feeding conditions, sexual reproduction occurs in some Hydra Instead, they spawn, meaning that they release their eggs and sperm into the water, reproducing sexually. In particular, Sea Urchins leave reproduction to chance. They do not select a mate, but rather release their gametes and leave it to chance that they will mix and get fertilized. Only 10% to 40% of eggs get fertilized Flamingo chicks mature quite rapidly - this is necessary to their survival. They can start leaving the nest after nearly 7 days. It is only a few months later that they are swimming and learning to fly. Chicks reach sexual maturity by 6 years of age. At that time, they can start mating and having chicks of their own . Unlike seed plants, though, mosses have flagellated sperm that must swim to fertilize an egg. That's one reason they can only survive in moist environments. In early spring, raindrops splash sperm from male plants to female plants

Both species reproduce by cyclical parthenogenesis, in which phases of asexual reproduction are intermitted by sexual reproduction. She does reproduce some of his more subversive etchings, although as plates, rather than prints Sea cucumbers exhibit sexual and asexual reproduction. Unlike most terrestrial animals, sea cucumber eggs undergo external fertilization—females release eggs into the water that are fertilized when they come into contact with sperm that males have released. In order for this form of reproduction to be successful, many males and females must.

It gives offspring the genetic traits to survive in a particular environment C. It uses less energy D. All of the above 2 See answer In the wild they usually reproduce sexually, but females in captivity have been known to reproduce by parthenogenesis, without the need for sperm. Female Komodo dragons lay a clutch of 15 to 30 leathery shelled eggs in the nest. There is no maternal care of the young they might eat their own young
How do snakes mate and reproduce? Are they asexual or sexual
As we have previously mentioned, sexual reproduction is a type of reproduction where there is a fusion of gametes, resulting in an offspring that is genetically different to its parents. The characteristics that define this type of reproduction are various. In the first place, in sexual reproduction there are two individuals involved, unlike asexual reproduction, a female and a male Whale Reproduction and Care of Young. Male whales are mature between 7 and 10 years of age. They have a cavity that their genitals remain in during resting and swimming so there isn't a great deal that is known about them in great deal. For females maturity occurs about 5 to 7 years of age. A female that is mature will generally have a new. Most animals that reproduce asexually are very small or even unicellular. Animals like the Hydra and Flat worm etc. reproduce asexually. While animals such as fish (salmon), humans, etc. reproduce sexually. Lots of plants, however reproduce sexually and asexually. Garlic produces seed (sexual) and bulbs (asexual) Reproduction in plants •Depending on the species, plants can reproduce both sexually and asexually. •Example: the lilac tree •The growth of several shoots at the base of the tree is an example of asexual reproduction. •In the spring, this tree also grows many flowers that will produce seeds, which is an example of sexual reproduction in plants known as flowering The polyps can then reproduce asexually by budding off tiny jellyfish one or two millimetres across, which feed on plankton and gradually grow into full-size adult jellyfish.

Like many jellies, sea wasps have an interesting life cycle that includes a combination of sexual and asexual reproduction. Sexually mature sea wasps are the jellies (known as medusae), with stinging tentacles, with which we are most familiar. These adults reproduce via external fertilization, where females release eggs and males release sperm. On this it may alternate between sexual and asexual generations (holocyclic) or alternatively, all young may be produced by parthenogenesis, eggs never being laid (anholocyclic). Some species can have both holocyclic and anholocyclic populations under different circumstances but no known aphid species reproduce solely by sexual means. [50
It has a lot to do with the much greater likelihood that a young chimp will survive to adulthood and how only a small percentage of turtle hatchlings will survive to reproduce. Some lizards, such as whiptails of the genus Cnemidophorus, reproduce asexually, but they do not lay any more eggs than sexually reproducing members of the same genus 12 October 2007 false killer whales, politics and life asexual-reproduction, science, sex James Graham I, for one, welcome our new asexual overlords Humans and most other types of organism reproduce sexually Bacteria and plants can reproduce asexually to produce genetically identical individuals.
