'Genetic polymorphism' diaporamas de présentation

Introductory Questions #32

Introductory Questions #32. How can allele frequencies change in a population and increase variation? Give three examples. What do we call this when this is happening? Does natural selection operate directly on the phenotype or genotype of organisms? Briefly explain your choice.
