A) double dominant genes
B) plastid genes
C) complementary genes
D) homeotic genes
Correct Answer: D
Solution :
Homeotic genes are control genes which either by getting expressed or by remaining silent during development, influence the differentiation of organs. These have been found in insects, one nematode and some plants. A DNA sequence called homeobox, present in these genes, is involved in specification of organs. A mutation that causes a body part to develop in an appropriate position in an organism, is called homeotic mutation e.g., in Drosophila, such mutation may cause legs to develop on the head in place of antennae.You need to login to perform this action.
