In fruit flies, pattern formation during embryonic development is based on ____.
A)a promoter and one or more operators
B)post-translational modification
C)RNA interference
D)dosage compensation
E)a gradient of maternal effect gene products in the embryo

Question

Quizplus · Accepted Answer

Fruit fly pattern formation during embryonic development is based on a gradient of maternal effect gene products in the embryo. Maternal effect genes are expressed in the mother and produce mRNAs and proteins that are deposited in the developing egg. The gradient of maternal effect gene products helps to determine the development of the head and tail regions of the embryo as well as the segmentation of the body.
