Does sexual reproduction result in more genetic variation in a species than asexual reproduction?
Wiki User
∙ 8y ago
Asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). Sexual reproduction produces a random mixture of the genetics derived from both parents.
In sexual reproduction, offspring are not identical to either parent.

How can this asexual reproduction be harmful to species?
Asexual reproduction does not allow for bio-diversity. Therefore if a disease comes along and effects one of them, the entire species will be very susceptible to the same disease, and entire species can be wiped out
In what situations might the genetic variations that result from sexual reproducion be better than asexual reproduction?
Sexual reproduction creates variations in species. This creates immunity.Asexual reproduction does not do this and just clones. The organisms splits its DNA in two. Stick insects are one example. This is a problem if a disease is in one Stick insect then there is a large risk that the hole population will die
An advantage of asexual reproduction is that?
that you get a baby. or that you need a partner
Is asexual reproduction or sexual reproduction more beneficial to the population?
Sexual reproduction is more beneficial to a species than asexual reproduction. This is because in sexual reproduction, the genes from two distinct parents are passed down to one distinct child, which creates genetic diversity. It also reduces the risk of mutations, and allows an organism to inherit more traits that could be beneficial to the species.
Why is sexual reproduction better than asexual reproduction for ensuring survival of a species in a changing environment?
Yes. Sexual reproduction is more advantageous than asexual reproduction in a challenging environment since sexual reproduction introduces more variation in the offspring. In asexual reproduction, the variation in offspring is caused by mutations and they are rare and a large number of offspring will have to be produced to ensure enough offspring with beneficial mutations are born, and this is not always possible when resources are scarce. In sexual reproduction, variation is introduced by recombination in addition to mutation, and recombination (random crossover of chromosomes) happens in every time the organism reproduces to introduce variation that may not be present in the parents. The greater amount of variation increases the chance of having offspring that are adapted to the challenging environment.
Dinobryon is a species of protozoa that reproduces asexual. How can this asexual reproduction be harmful to the species?
They have less genetic diversity in their population.
Why is sexual reproduction preferable to a species?
It promotes genetic variation.
Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
Dinobryon is a species of protozoa that reproduces asexually . How can this asexual reproduction be harmful to the species?
They have less genetic diversity in their population.
What Dinobryon is a species of protozoa that reproduces asexually How can this asexual reproduction be harmful to the species?
Dinobryon is a species of protozoa that reproduces asexual. This can be harmful to the species because they have less genetic diversity in their population.
How can this asexual reproduction be harmful to species?
Asexual reproduction does not allow for bio-diversity. Therefore if a disease comes along and effects one of them, the entire species will be very susceptible to the same disease, and entire species can be wiped out
Why does sexual reproduction result in genetic variation in a species?
It mixes the chromosomes of the two parents
What are the two forms of repoduction?
Reproduction occurs in two main types sexual and asexual. Asexual is the reproduction in which involves only one individual from a species. Most Asexual reproduction occur in single cell organisms. Example of asexual reproduction can be found in self pollinating plants. Sexual reproduction occurs when two individuals trade genetic information to produce a new individual for a species.
What might be the evoluntionary significance of the swicth from asexual to sexual reproduction when the environment changes?
Environmental changes almost demand variation in organisms so that the best fitted to the changing environment survive and reproduce in a greater number. Asexual reproduction produces clones with little to no genetic variation. Good enough for a static environment, but in a challenging environment with no variation that could be more beneficial than cloning the asexual species could find itself selected against.
Does asexual reproduction limits the spread of detrimental characteristics through a species and allows for genetic continuity?
yes
Explain how a species can reproduce asexually How does this impact genetic variation?
the cell goes through mitosis (interphase, metaphase, anaphase, telophase) and it splits into two identical cells (during this process the DNA is duplicated). As a result of asexual reproduction, there is no variation in population.
Why does sexual reproduction the genetic variation in a species?
A fertilized egg has a mixture of alleles from the two parents.
