Question

The part of the Drosophila zygote with high bicoid concentration will

A. become the anterior region of the embryo
B. become the region of the embryo that has a spiracle
C. become the tail region of the embryo
D. become the segment that will have wings
E. become the segments that will have legs

Answer 1

The part of the Drosophila zygote with high bicoid concentration will become the anterior region of the embryo.

Step-by-step explanation:

The part of the Drosophila zygote with high bicoid concentration will become the anterior region of the embryo. Bicoid is a protein that is involved in establishing the anterior-posterior axis of the embryo. This protein is initially localized at the anterior end of the egg and then gradually diffuses toward the posterior end, resulting in a concentration gradient.

The high concentration of bicoid at the anterior end leads to the development of structures specific to that region, such as the head and thoracic segments.
