Question

Why does genetic drift affect a

small population more than a
large one?
A. small populations have more diversity than a
large population
B. the loss of a few alleles causes a large shift in
the allele frequency of a small population
C. large populations have more allele diversity
so a dramatic event would result in more loss

Answer 1

B

Step-by-step explanation:

Genetic drift is more important in small populations because the chances of an allele being lost or fixed in the population are much higher, this is because each individual in a small population represents a larger proportion of the entire population (than in a large population).
