Hardy–Weinberg assumptions
Which situation violates an assumption of Hardy–Weinberg equilibrium?
Answer D: explanation for every choice
A
A very large population is one of the assumptions, because it minimizes genetic drift.
B
Random mating is an assumption.
C
No mutation is an assumption.
D
Correct. Migration introduces alleles (gene flow) and changes allele frequencies.
TakeawayHardy–Weinberg needs a large population, random mating, and no mutation, migration, or selection.
