|
sexual reproduction |

mutation |
Homework Answers
Option d is correct. Mutation adds new alleles to the gene pool of a species. Mutation is the ultimate source of new genes as a change in a DNA sequence leads to new alleles.

One of the touted advantages of sexual reproduction is the clearance of deleterious mutations. What mechanisms are involved in clearance? Describe them and illustrate the process by which a deleterious mutation—say, the allele Abad—is cleared. Why doesn’t clearance typically occur in asexual species?

Assortment of genes on same chromosome In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another gene locus. there is a dominant gene for red eyes and its recessive allele for purple eyes. A female that was heterozygous at both gene loci was mated with a male that is homozygous for both recessive alleles. Knowing this, complete the sentences with the correct terms. 94% crossing over independent assortment...
