What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
How does sexual reproduction affect genetic traits?
Asexual reproduction impacts genetic variation by limiting future genetic change to mutations only; sexual reproduction allows future generation to mix in a nearly infinite range of phenotypes (external appearance).
Which of these is not a source of genetic variation in a population?
The answer is sexual reproduction
What are the two main sources of genetic variation and which of them is more common?
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
Give an example of how sexual reproduction increases genetic diversity?

Why is sexual reproduction a source of genetic variations?
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population.
Which does sexual reproduction create new alleles or new combination of allele?
Sexual reproduction creates a new combination of alleles.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
What determines an organisms alleles in sexual reproduction?
An organism's alleles in sexual reproduction are determined by the combination of alleles inherited from its two parents. Each parent contributes one allele for each gene, leading to genetic diversity in the offspring. Random assortment and recombination of alleles during meiosis further contribute to allele variation.
Does sexual reproduction create new alleles or new combinations of alleles?
new combinations of alleles
Which does sexual reproduction create new allels or new combinations of alleles?
new combinations of alleles
Who gives alleles?
Organisms inherit their alleles from their parents. In sexual reproduction, the alleles are usually inherited from two parents. In asexual reproduction, the alleles are inherited from a single cell and are genetically identical to the parent.
How traits are inherited through alleles?
By sexual reproduction the parental alleles through gametes are inherited in the subsequent generation
Does alleles fuse during self-pollination?
No, alleles do not fuse during self-pollination. Self-pollination involves the transfer of pollen from the anther to the stigma of the same flower or between flowers of the same plant. The fusion of alleles occurs during sexual reproduction when gametes from two different individuals combine to form a zygote with a unique combination of alleles.
Why does sexual reproduction the genetic variation in a species?
A fertilized egg has a mixture of alleles from the two parents.
Why does sexual reproduction increase the variation in a species?
A fertilized egg has a mixture of alleles from the two parents.
Would you get a variety of offspring traits during asexual or sexual reproduction?
Sexual reproduction promotes variation.
