Document Summary
Populations are simply collections of families, thus mendel"s principles can still be applied. Product rule still works to predict genotype frequencies, but allele frequencies not always. In a large, random-mating population, where mutations are rare enough to be ignored, in the absence of immigration or emigration, and if there is no selection . After one generation of random mating, genotype frequencies predictable from allele frequencies. To recognize evolution, we need to know what a non-evolving population looks like. If genotype frequencies can be predicted from allele frequencies, population is in hardy- Allele frequencies will not change while this is true. Average number of surviving offspring, for a particular genotype. What are some factors that affect absolution fitness. Standardize absolute fitness (w) to get relative fitness. Strength of selection reflects how much genotype will differ in relative fitness. Different results when dominant and recessive alleles are selected against:
