Altering Existing Genetic Variation
Genetic Drift
Genetic drift is a change in in genetic variation due to chance changes in allele frequencies. For example, genetic drift may occur as a matter of luck; one phenotype may simply never meet a member of the opposite sex in order to mate and produce offspring. Genetic drift is not affected [...]
Population geneticists primarily study allele and genotype frequencies. They use quantitative methods to analyze the frequency of alleles. For example, a population geneticist may study the frequency of certain patterns on the fur of wild cats, then will revisit the same population several generations later to find how the frequency of patterns has changed from [...]
Species- a natural group that shares a distinct form
Population- a group of individuals of the same species that live in the same environment and can interbreed with each other
Gene pool- all the genes and all the alleles of those genes that exist in a population
