Question

In Drosophila, the homeotic genes act in combination to specify the identity of the 14 body segments. Two clusters of homeotic genes have been found on chromosome 3: the______complex consists of five genes, and the_______complex consists of three genes.

Answer 1

The Antennaapedia which comprises of five genes and Bithorax complex which consist of three genes.

Explanation:

Drosophilia has eight hox genes which are clustered into two complexes, both located on chromosome 3. The Antennapedia complex which comprises of five genes namely: Labial (Lab),proboscipedia(pd), deformed(Dfd), sex combs reduced(Screen), and Antennapedia(Antp). The Bithorax complex which comprises of the remaining three genes namely: Ultrabithorax(Ubx), abdominal-A (abd-A), and abdominal-B (abd-B).

Answer 2

In Drosophila, the homeotic genes act in combination to specify the identity of the 14 body segments. Two clusters of homeotic genes have been found on chromosome 3: the Antennapedia complex consists of five genes, and the Bithorax complex consists of three genes.

Step-by-step explanation:

The Hox genes are critical developmental genes that specify the body plan during animal embryo development. The antennapedia and bithorax complexes localized in the chromosome 3 contain Hox genes that regulate the development of body segments in fruit flies
