Suppose you found several Drosophila mutants that possessed additional legs growing out of their head segments. The probable mutation would be found in ________.
A) segment-polarity genes
B) gap genes
C) pair-rule genes
D) homeotic genes

Question

Quizplus · Accepted Answer

The development of specific body parts is controlled by homeotic genes. A mutation in these genes can result in a change in the identity of a segment, causing the development of abnormal body parts. In this case, the mutation resulting in the growth of extra legs on the head segments suggests a mutation in the homeotic genes.
