Front | What is genetic drift |
---|---|
Back | Individuals within a population show variation in their genotypes By chance the allele for one genotype is passed on to the offspring more often than others Number of individuals with the allele increases Changes in allele frequency in two isolated populations could eventually lead to reproductive isolation and speciation Evolution by genetic drift has a greater effect in smaller populations where chance has a greater influence |
