Question

Gap genes and pair-rule genes are examples of genes that determine ________.
A) the formation of body segments
B) the formation of the primary cell layers
C) the formation of cellular adhesion
D) the formation of the major body axis

Accepted Answer

Gap genes and pair-rule genes play a critical role in the determination of body segments during development. Gap genes are expressed early in development and regulate the formation of broad regions along the body axis, while pair-rule genes are expressed later and determine the boundaries of specific segments within these regions. Therefore, the correct answer is A) the formation of body segments.
