Population Genetics
Objectives:
After completing this section, you should:
1. Define a population
2. Define allele frequency
3. Define gene pool
4. Define mating system
5. Contrast population genetics with family genetics
6. Calculate genotype and allele frequencies from population genetics data
7. Determine if the genotype and phenotype frequencies observed in a
population are consistent with a proposed mating system for that trait in the
population.
8. Predict how a population will change given a change in a population’s
mating system or a change in selection pressure for a specific trait in the
population.
