Listed below are some sex chromosome combinations. For each combination, state whether the individual is male or female in humans and also in Drosophila (assume the flies have two sets of autosomes). Please answer with either the word male or female (not metafemale or metamale).   Chromosomes Biological Sex in Humans Biological Sex in Drosophila XXX XY XO XXY XX     What would be the biological sex of a human XXY individual with a mutation in the SRY gene (assume the mutation leads to a completely nonfunctional SRY protein)? How many Barr bodies would be present in the cells of an XXX individual?

In Drosophila, white eyes (Xw) result from an X-linked allele that is recessive to the allele for wildtype red eyes (Xw+). Give the most likely genotypes of the parents in each of the following crosses. Please use the following notation for the alleles: Xw (white-eyed allele) and Xw+ (wildtype red-eyed allele) and indicate genotype without space between alleles/chromosomes (e.g. XwXw). Don’t forget that males have a Y chromosome!     Male Parent Female Parent Male Offspring Female Offspring Cross #1 White Red 625 Red 630 Red Cross #2 Red White 556 White 576 Red Cross #3 White Red 231 Red 250 White 224 Red 234 White   Genotype for male parent #1: Genotype for female parent #1:    Genotype for male parent #2:  Genotype for female parent #2:   Genotype for male parent #3: Genotype for female parent #3:
