Verified
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
Pattern Formation
The biological process by which cells in an organism acquire different identities, leading to the emergence of patterns such as stripes or spots during development.
Maternal Effect Gene
A gene whose expression in a mother affects the phenotype of her offspring, independent of the offspring's genotype.

Final Answer :
E
Explanation :
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.
