Hardy Weinberg Equilibrium Flashcards
what does it sayq
the frequency of alleles will stay the same throughout generations if a population is stable and in genetic equilibruim
five conditions for HW equilibruim
1) large breeding population
2) no immigrants/emigrants
3) no change in allelic frequency
4) random mating
5) no natural selection
what is a population bottleneck?
sharp reduction in size of pop due to random event (envionmental or human activities)
what is the founder effect?
the loss of genetic variation that occurs when a new population is established by a small # of individuals
what is the HWequation
P^2+2pq+q^2=1
what does p represent
frequency of dominant allele
q=
frequency of recessive allele
p^2
frequency of homo dominant genotype (AA)
q^2
frequency of homo recessive genotype (aa)
2pq=
frequency of heterozygous genotype (Aa)
