Which process most often results in offspring with the same DNA as the parent cell?
What produces cells identical to the parent cell?
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies – or ‘replicates’ – its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
What process must the cell undergo to have genetically different cells?
Which process must the cell undergo to have identical?
Which is a disadvantage of asexual reproduction Brainly?
A disadvantage of asexual reproduction is that the offspring are genetic clones and there is lack of genetic variation among the offspring.
What are 3 disadvantages of asexual reproduction?
What Are the Disadvantages of Asexual Reproduction?
- Negative mutations linger longer in asexual organisms.
- Diversity is limited.
- Population numbers can be difficult to control.
- There can be an inability to adapt.
- Overcrowding can be a real issue.
- Reproduction can create competition.
Which is an example of asexual reproduction by regeneration?
Regeneration is a type of asexual reproduction in which the organism is capable of regrowing certain body parts. Regeneration occurs via mitosis. Lizards can regenerate their tails, star fish can regenerate their arms while humans have the ability to regenerate their liver to a certain extent.
What is an example of regeneration?
Regeneration is the act or process of coming back, growing anew or a spiritual rebirth. When a lizard loses its tail and then grows it back, this is an example of regeneration.
What can reproduce asexually?
Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.
What do all types of asexual reproduction have in common?
All these variations of asexual reproduction have one thing in common, the offspring is a direct clone of the parent. The purpose of reproduction is to propagate one’s own genes. Evolutionarily, asexual reproduction is a good deal for the parent.
Is asexual reproduction fast or slow?
Asexual reproduction can be very rapid. This is an advantage for many organisms. It allows them to crowd out other organisms that reproduce more slowly. Bacteria, for example, may divide several times per hour.
What is an advantage of asexual reproduction?
The advantages of asexual reproduction include: the population can increase rapidly when the conditions are favourable. only one parent is needed. it is more time and energy efficient as you don’t need a mate. it is faster than sexual reproduction.
What would happen if there was only asexual reproduction?
If the organisms of a species all fail to reproduce then the species may become extinct. Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents.
What animals can reproduce without a mate?
Greenflies, stick insects, aphids, water fleas, scorpions, termites and honey bees are all capable of reproducing without males, using parthenogenesis.
Can female reproduce by themselves?
Females can potentially switch between sexual and asexual reproductive modes, or reproduce entirely asexually, but males cannot clone themselves. While parthenogenesis makes it possible for females to reproduce without males, males have no way to reproduce without females.
What could be the effect if humans reproduce asexually?
Because humans produce asexually, no sexual reproduction could occur, and hence a second sex would not be needed. Everyone would be essentially a female. Second of all, everyone would have the exact same genetic code, except for perhaps small variations due to random mutation.
Can a girl get pregnant without losing her virginity?
The answer is — yes! While it isn’t likely, any activity that introduces sperm to the vaginal area makes pregnancy possible without penetration.
Can a hermaphrodite make a woman pregnant?
Fertility. There are extremely rare cases of fertility in “truly hermaphroditic” humans. These individuals typically have functional ovarian tissue, but underdeveloped testes that are unable to engage in spermatogenesis. As a result, these individuals are fertile, but not auto-fertile.
Can female bone marrow produce sperm?
Female sperm Nayernia says that researchers have produced the same early-stage sperm cells in mice from bone marrow cells taken from female mice. “It should be perfectly possible for fully functional mature sperm cells to be made from these female-derived cells too,” he told New Scientist.
Can a woman produce sperm?
Scientists have been skeptical that sperm can be produced from female cells, which lack a Y chromosome and thus whichever Y-linked genes are crucial to sperm production.
