The correct answer that would best complete the given statement above would be A TWO-HEADED FLY. A high concentration of bicoid protein at the opposite ends of a developing drosophila embryo would result in the development of a two-headed fly. The bicoid <span>gene is a type of egg-polarity gene and is transcribed by nurse cells. </span>
<span>The answer is A. Variation in gene pool
Speciation is a formation of a new species during the evolution line.
When there is a variation in a gene pool, a unique combination between genes could be formed during the mating process. This will create an offspring with unique gene pool that will lead to speciation</span>
