In drosophila white eye is inherited as a sex linked, Ask an Expert

Academics

In Drosophila, white eye is inherited as a sex linked recessive condition x superscript w. At another locus, sepia eye s is inherited as an autosomal (non sex linked) recessive. The presence of the white eye phenotype (x superscript w x superscript w in females, x superscript y in males) masks the sepia phenotype, so regardless of the sepia genotype, the fly's appearance will be white. Cross whited eyed males who are heterozygous at the sepia locus with wild (red) females who are heterozygous at both loci. What phenotypic ratios are produced (a) among male offspring (b) among female offspring?
