WebIn Drosophila melanogaster, most cells make this choice independent of their neighbors such that diploid cells with one X chromosome (XY) are male and those with two X chromosomes (XX) are female. X-chromosome number is relayed through regulatory proteins that act together to activate Sex-lethal (Sxl) in XX animals. WebIn fact, in Drosophila, sex is primarily determined by the X:A ratio, or the ratio of the number of X chromosomes to the number of sets of autosomes (Cline & Meyer, 1996).
