In Drosophila,a developmental mutation called ssᵃ (spineless aristapedia)results in flies with mini leg parts on the antennae.What kind of gene is this mutation?
A)gap gene
B)pair-rule gene
C)homeotic gene
D)segment polarity gene
E)maternal effect gene

Question

Quizplus · Accepted Answer

Homeotic genes are responsible for determining the identity of body segments and regulate the development of body parts. The mutation resulting in antennal leg parts indicates a change in the identity of the antennal segment, indicating a homeotic mutation. Gap genes, pair-rule genes, segment polarity genes, and maternal effect genes are not directly involved in specifying body segments or body part identity.
