Which of the following factors does not favor a change in gene frequency and, therefore, evolution?
A. Large populations
B. Mutations
C. Emigration
D. Genetic drift
E. All of the above
Answer (2)
Genetic drift does not favour a change as it is all about the variation of genes within a SMALL population; smaller population = smaller variation of genes
All the rest do favour a change in gene frequency
The factor that does not favor a change in gene frequency is A. Large populations, as they tend to maintain genetic stability. In contrast, mutations, emigration, and genetic drift can all lead to changes in gene frequency. Therefore, large populations do not drive evolutionary change.
