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

Question

Quizplus · 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.
