In Drosophila sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. Female ratio is 1 or greater, males have a ratio of 0.5 or less. Identify sex of following flies XY fly with 2 sets of autosomes ______________ XXY fly with 2 sets of autosomes ______________ XX fly with 3 sets of autosomes ______________
