Answer: Option A
Explanation:
A morphogen gradient is an important concept in case of the developmental biology. It produces the signals from the part of embryo which decides the fate of development of the parts.
The differentiation of the cell takes place by the help of the signals produced by the embryo in order to decide where will which part of the embryo grow.
The surrounding cells receive the signals and the development of entire body parts takes place.
So, the mutation in this gene will transform the entire body part.
Answer: Option A.
Explanation:
Morphogens are signaling molecules that originate from a specific location that spread from their origin via diffussion to form a concentration gradients acting at long distances to induce responses in cells base on the gradients the cells interact with. It determines the pattern of tissue development and morphogens gradients cause the differentiation of unspecialized stem cells into different cell types.
