Question

) In Drosophila, the sequential order of the function of segmentation genes is ________.

A) gap, segment-polarity, pair-rule
B) pair-rule, transdeterminal, gap
C) transdeterminal, gap, pair-rule
D) gap, pair-rule, segment-polarity
E) segmentational, helical, spherical

Answer 1

In Drosophila, the sequential order of the function of segmentation genes is gap, pair-rule, segment-polarity.

Step-by-step explanation:

In Drosophila, the sequential order of the function of segmentation genes is gap, pair-rule, segment-polarity. Gap genes are responsible for dividing the embryo into broad regions, pair-rule genes establish the body segments, and segment-polarity genes determine the anterior-posterior polarity of each segment.
