- Natural Selection Affects the Frequency of Genetic Disorders Will a recessive allele that is lethal in the homozygous condition ever be completely removed from a large population by natural selection?How can natural selection favor different phenotypes at different times?Why do traits have to be heritable in order for evolution by natural selection to occur?
- Why is the elimination of a fully recessive deleteriousallele by natural selection difficult in a large populationand less so in a small population?What is the difference between natural selection and sexual selection?Natural selection means that the environment favors survival of some genotypes. From where does diversity in genotypes come?
