Topic 7.5 - Hardy Weinberg Equilibrium Flashcards
1
Q
Hardy Weinberg model
A
describes and predicts the frequencies of alleles in a nonevolving population
2
Q
what happens in a hardy weinberg environment
A
the frequencies of alleles stay the same generation after generation
3
Q
what 5 conditions must be met for a population to be in Hardy-Weinberg equilibrium?
A
❥ large population
❥ absence of migration
❥ no net mutation
❥ random mating
❥ absence of selection
4
Q
what do these conditions provide?
A
a valuable null hypothesis
5
Q
what factors disrupt equilibrium and change allele frequencies in a population?
A
❥ mutations
❥ non-random mating
❥ gene flow
❥ genetic drift
❥ natural selection
