A) Maternal effect genes
B) Gap genes
C) Pair rule genes
D) Segment polarity genes
E) Hox genes

Question

Quizplus · Accepted Answer

Gap genes are responsible for dividing the broad areas along the anterior-posterior axis into smaller regions, which are then further refined by the pair rule genes and segment polarity genes. Maternal effect genes are involved in establishing the gradients of signaling molecules that specify the initial pattern of gene expression, while Hox genes are responsible for specifying the identity of each segment along the anterior-posterior axis.
