Question

Explain Maternal effect mutants affecting AP axis patterning

Expert Solution

Step 1

The fruit fly Drosophila melanogaster is well suited to genetic screens because their phenotypes are easy to observe, and since they possess only 4 pairs of chromosomes, it is even more easier to map and characterize their single genome. The cells that arise by cell division from the zygote (fusion of male sperm and female egg) have to become different to each other over time. Accessing the developmental genes plays an important role in guiding the development to find out what kind of gene products the developmental genes encode and lead to their distinct phenotypic expression.

“In the early Drosophila embryo, the establishment of different body regionor tissues along, on the one hand, the anteroposterior axis and, on theother, the dorsoventral axis are initiated by clues provided by the egg’smother; however the nature of those signals and the way in which theyoperate is completely different”. Discuss whether this statement is correct.
