UPDATE
Population
group of individuals of same species living in same area
- interbreed, producing fertile offspring
Population genetics
study of processes that change allele & genotype frequencies in populations
How do we get changes in allele frequencies?
1. Mutation modifies allele frequencies by continually introducing new alleles
2. Genetic drift causes allele frequencies to change randomly
3. Gene flow individuals leave one population, join another, & breed
4. Natural selection increases frequency of alleles that contribute to reproductive
success in a particular environment
- only natural selection produces adaptation
Mendel
consequences of mating two individuals with certain genotype
Hardy & Weinberg
