Why does sexual reproduction result in more genetic variation in a species than asexual reproduction?

In asexual reproduction there are 2 daughter cells produced that are identical to the parent cell. In sexual reproduction there are 4 genetically different daughter cells produced that are haploid (23 chromosomes). Crossing over occurs during meiosis which mixes up segments of DNA on homologous chromosomes causing new genetic variations. By the sperm fertilizing the egg, you are combining 2 completely different sets of different haploid DNA to produce a diploid offspring which is genetically different from both parents.

∙ 8y agoAsexual 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.

A fertilized egg has a mixture of alleles from the two parents.

It mixes the chromosomes of the two parents.

∙ 14y agoI'll use the examples from humans: In human gametes, there are 23 chromosomes and gametes are considered haploid cells because they have half of what the other body cells have. When fertilization occurs, genetic material from both the MOTHER and the FATHER are mixed together. Asexual reproduction only involves the genetics from one of the parents.

Does sexual reproduction result in more genetic variation in a species than asexual reproduction?
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.
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.

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.
