The product of the bicoid gene in drosophila provides essential information about
a) the dorsal-ventral axis
b) the left-right axis
c) segmentation
d) the anterior-posterior axis

The correct answer is: D) the anterior-posterior axis

Bicoid gene encodes for the protein that is very important for embryogenesis of Drosophila. Bicoid protein concentration gradient patterns the anterior-posterior (A-P) axis or simply saying determines which end is the front end of the embryo.

Bicoid gene is maternal-effect gene meaning that zygote inherits the Bicoid directly from its mother.
