- Study of what happens to whole populations at the genetic level
- Population Genetics
- group of interbreeding individuals that occupy the same space
- Population
- alterations of a populations gene pool - changes allele frequency
- Microevolution
- proportion of individuals that have a particular phenotype
- Phenotype frequency
- proportion of individuals that have a particular genotype
- genotype frequency
- proportion of all copies of a gene in a population that are of a given allele type
- Allele Frequency
- Hardy-Weinberg Law
- -predict potential incidence of recessive -correlates allele/genotype frequencies -predict allele/genotype frequencies
- H-W Law Assumptions
- -infinite # of individuals -mating is random -no mutations in gene pool
- changes in allele frequency in a population over multiple generations
- Evolution
- evolution over geologic time
- Macroevolution
- Natural Selection
- process that progressively eliminates individuals whose fitness is low and chooses individuals of high fitness to survive
- ability to survive and reproduce
- Fitness
