Note: Gender in fruit flies is determined by the composition of the sex chromosomes, X & Y; females are XX and males are XY. In fruit flies, a new mutant phenotype called wingless (i.e. a fly with no wings) is found to be a recessive phenotype, while having wings is the wildtype (and dominant) phenotype. This trait is X- linked. A female that is homozygous with wings is mated to a male fly that is wingless. The F1 are intercrossed to produce an F2 generation. what is the genotype of female? xt xt xw xw WW ++ xt xw
