Question

Which of the following describes how self-fertilization differs from asexual reproduction?

A. They are not different

B.Self-fertilization involves meiosis and recombination, allowing for deleterious alleles to be purged; asexual reproduction does not

C.Self-fertilization allows for purging deleterious alleles, but does not break down linkage disequilibrium; asexual reproduction does not allow for either

D. Self-fertilization requires a partner, allowing for an exchange of chromosomes; asexual reproduction does not

Answer 1

ANSWER: The correct alternative is (B) Self fertilization involves meiosis and recombination , allows for deleterious alleles to be purged and asexual reproduction do not. Self fertilization is aprocess of meiotic recombinatiom which involves the union of male and female gamete from the same organism.This further leads to inbreeding depression allowing the purge of the deleterious alleles. However asexual reproduction requires extenive cell proliferation and thus stick to mitosis.
