D) alleles in populations.
E) All of these

Question

Quizplus · Accepted Answer

Natural selection refers to the process where certain traits or alleles become more common in a population due to their fitness advantage, which leads to higher survival and reproduction rates. At the level of the gene, natural selection acts on specific alleles, and thus changes their frequencies in populations. Therefore, the correct choice is D - natural selection changes the frequencies of alleles in populations. The other choices (A, B, C, and E) are not accurate because they refer to either genotypes (A and B) or biomes (A and C), which are not directly affected by natural selection at the gene level.
