← Nature & AnimalsWhich hunting outcome occurs in peppered moths as industrial pollution darkens tree bark?
A)Directional selection increases melanism frequency✓
B)Genetic bottleneck reduces species diversity
C)Founder effect amplifies rare alleles
D)Gene flow prevents local adaptation
💡 Explanation
Directional selection increases melanism because camouflage against dark bark improves survival and reproduction; therefore, darker moths become more common, rather than diversity reducing from bottlenecks or impeded adaptation from gene flow.
