In 1921 it was discovered that the sexual fate of Drosophila is determined by the ratio of X chromosomes to sets of autosomes. Only recently has it been found that the X chromosome to autosome (X:A) ratio is communicated in part by the dose of sisterless-b (sis-b), an X-linked genetic element located within the achaete-scute complex of genes involved in… CONTINUE READING
