Irregularity is found in Drosophila during the organ differentiation, for example in place of wings, long legs are formed. Which gene is responsible :
A
Double dominant gene
B
Homeotic gene
C
Complementary gene
D
Plastid
Detailed Solution
Homeotic genes (Hox genes) control the identity of body segments and the development of organs at their proper places during development.
Mutations in these genes cause one body part to develop in place of another: e.g. in the Antennapedia mutant of Drosophila, legs grow in place of antennae, and in bithorax mutants an extra pair of wings forms.
So such irregularities are due to homeotic genes.
