Suppose you found several Drosophila mutants that possessed additional legs growing out of the 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

Homeotic genes control the overall body plan of an organism, including the identity of each segment. Mutations in these genes can cause changes in segment identity, such as the growth of legs in abnormal locations. The mutation described in the question is consistent with a homeotic gene mutation, specifically affecting the head segment.
