What is population genetics?
applies genetic principles to entire populations of organisms.
1 of 8
What is Mendelian population?
natural interbreeding unit of sexually reproducing plants or animals sharing a common gene pool.
2 of 8
What is subpopulation?
population unit aka local population
3 of 8
What is a gene pool?
all alleles in a population
4 of 8
What is genotype frequency?
proportion of individuals in a population with a specific genotype.
5 of 8
What is allele frequency?
proportion of each specific allele in a population.
6 of 8
When would allele and genotype frequencies remain the same?
when there is random mating, no mutations, no migration, no selection, no random genetic drift
7 of 8
What are the uses of HW principle?
determination of equilibrium by comparing the observed genotype frequencies with those expected from random mating,calculation of heterozygote frequencies for rare alleles as heterozygotes are more common than homozygotes
