Allele frequencies in a ❌ remain ❌ over time unless acted upon by evolutionary ❌.
Which of these is not an assumption of the Hardy-Weinberg equilibrium?
Large population size
No natural selection
No mating
No mutations
No migration
The frequency of alleles can be calculated by:
p + q = 100
p + q = 1
p^2 + 2pq + q^2 = 1
p^2 + pq + q^2 = 100
The genotypic frequency can be calculated by:
p^2 + pq + q^2 = 1
pq^2 + 2pq + q^2 = 1
p1^2 + p + q = 1

Genetic drift is a change in allele ❌ due to random, ❌ natural selection events.
Stabilising selection ❌ variation but ❌ change the mean. Directional selection ❌ the mean value toward an ❌. Disruptive selection ❌ the two extremes, and often leads to ❌.
