No. Genotype is the combination of genes present in an organism. It consists of alleles whose visible characteristics is called phenotype. An organism's phenotype is visible and not the genotype as you just can't see a person and tell what kind of genes are present in the organism.
Genetic variation is one of the conditions required for Natural Selection to occur.
A large population increases genetics variation. Mutation will also increase genetics variation.
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
Meiosis is responsible for genetic variation
If a population dwindles, there is low genetic variation and a species may risk extinction.
Loss of genetic variation(:Novanet:)
To see how people are different which usually we're all really the same.
The genes decide how we look and a lot about how we are. If there wasn't genetic variation we'd all be the same.
Basic source of variation in all organisms is mutation .
Human recombination is a significant source of genetic variation.
Natural and Artificial Selection
mutations cause genetic variation, and vice-versa. If there is a genetic variation (or lack of one), then this can effect the severity of the mutation.
Genetic variation
It increases genetic variation in organisms
Genetic variation allows a population to adapt to a changing environment.
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.
No, natural selection works on that genetic variation presented to it.
