The reason why some mutations, which are harmful, do not get eliminated from the gene pool is that
(a) they are recessive and carried by heterozygous individuals
(b) they are dominant and show up more frequently
(c) genetic drift occurs because of a small population
(d) they have future survival value

- Moumita Sen It's not the correct answer. The question applies to populations of all sizes, not just a small population.Upvote·0· Reply ·2013-04-04 05:32:44

- Moumita Sen This is not the correct answer either. Such a mutation would not survive because it is harmful and the individual having it would die or reproduce less, which would lead to the mutation being ultimately eliminated from the population.
