Question

Lou, a researcher, is examining two different fireflies, and each firefly is homozygous for a mutation that is inherited in an autosomal recessive manner. Lou has discovered that the two fireflies both show defects in flying. Lou would like to determine if both fireflies have mutations in the same or different genes, so he mates the two fireflies together. The resulting offspring all can fly normally. What would this result suggest? Select all that apply.

Group of answer choices

A) The two parent fireflies contain mutations in different genes

B) The two parent fireflies contain mutations in the same gene

C) This is an example of complementation

D) This is an example of the failure to complement

Expert Solution

Step 1

When a particular trait is autosomal recessive then it means if both the mutant alleles are present in an individual, then it will result in mutant phenotype. Having a single mutant allele in autosomal recessive manner will result in a normal phenotype due to the presence of another allele which is dominant and normal. In this question, two different fireflies are examined and they are homozygous for both the mutation. After mating both the flies, the offspring resulted was normal.
