Their mutation rates increase. The presence and distribution of alleles diverge. They respond differently to the same selection pressures. They interbreed to maintain uniformity of traits.
A geological change separates a wolf population into two new populations. Genetic drift directly causes which effect in the two new populations over time?

Options:
- Their mutation rates increase.
- The presence and distribution of alleles diverge.
- They respond differently to the same selection pressures.
- They interbreed to maintain uniformity of traits.

The presence and distribution of alleles diverge.
