alleryGenetic drift is STRONGEST in which type of population?
AVery large populations (millions of individuals)
BMigrating populations across continents
CRandom-mating populations of any size
DSmall populations (founder effect, bottleneck)
Answer & Solution
Correct answer: D. Small populations (founder effect, bottleneck)
Genetic drift = random changes in allele frequency by chance.
Its effect is much STRONGER in SMALL populations (statistical fluctuations matter more).
Bottleneck (population crash) and founder effect (small migrating group) are extreme cases.
