Breeding Population o Population is a group of organisms that tend to choose mates from within the group. Main thing is the ability to reproduce. Hardy- Weinberg o Evolution is the change is allele frequency. o The H.W equation relates allelic frequencies of the expected genotype frequencies of the offspring of heterozygotes. p^2 + 2pq + q^2 = 1 Assuming the following The population is large Mating is random No mutations Genes are not under natural selection So the difference between the expected genotype frequency and the expected genotype frequency can indicate whether evolution is occurring or not. o If the difference is greater than 10 percent., the population is then not in equilibrium. The reason can only be genetic if it is lower than .1 Fitness and Selection Coefficient o Fitness is the ratio of survival before and after selection. o The selection coefficient is the difference between 1 and the relative fitness.
