The determination of different genes which are expressed at higher levels in male Drosophila embryos and those genes that are expressed in the female drosophila embryos. After identification of sex-specific genes, plan the experiment to test the effect of these genes on the development of Drosophila sex organs. Introduction: The tissue and cell specific gene expression is a crucial feature of embryonic development in multi-cellular organisms. The spatial and temporal expression of gene patterns along with the extent of correlation of expression with function are under tight regulation. The embryonic expression patterns for different protein coding genes in the Drosophila melanogaster genome shows the detectable expression in embryo, like 20% patterned as early as in blastoderm stage. These specific genes are correlated with particular cellular and developmental functions.

Using this information, how do I figure out the answer to question1? INTRODUCTION In most species of Drosophila, a female mating with a single male usually supplies sufficient sperm to fertilize her lifetime supply of eggs. Moreover, mating is often costly to female flies. So why do females of some species mate more than once? Perhaps they do this to assess the quality of males and/or the sperm males produce via sperm competition. Tom Price, Nina Wedell, and their colleagues at the University of Exeter provide evidence for the sperm competition hypothesis. They show multiple mating increases in frequency when a selfish genetic element that reduces sperm quality is prevalent. In Drosophila, females are XX and males are XY. They normally occur in equal numbers. In D. pseudoobscura, males that harbor the X-linked selfish genetic element sex ratio (SR) have produced nearly all female progeny, as SR sabotages Y-bearing sperm. The SR element gains a tremendous transmission advantage but…
