When the Bicoid protein is expressed in Drosophila, divisions between cells in the embryo are not yet fully developed. This helps to explain that (B) Bicoid protein diffuses throughout the embryo in a concentration gradient.
Bicoid protein acts as a morphogen. This means it shows its effect when the concentration gradient is high. Also abbreviated as Bcd, the protein helps in establishing the anterior and posterior region of the Drosophila. It also represses the translation of caudal mRNA.
Embryo is the initial stage of a microorganism, right after the fertilization. In vertebrates, this stage does not last much longer because the development of organs begins.

Answer:
The answer is:
D. A mutation causing uncontrolled cell division.
Uncontrolled cell division is very dangerous and harmful to an organism, it can cause diseases such as cancer. Hope that helps. :)
Highly conserved genes are important for normal function of the organism of every species from prokaryotes to eukaryotes. So such genes do not mutate easily and are highly preserved.
