Question

In Drosophila, the white gene located on the X chromosome affects eye color; an autosomal gene, wingless, is on an autosomal chromosome.

Use the following allele symbols:

Xw+ _ ,  Xw+Y = wild type red eyes; X-linked dominant allele

Xw Xw , XwY = white eyes; X-linked recessive allele

Y = Y sex chromosome

vg+ = wild type wings; autosomal dominant

vg = wingless; autosomal recessive

Predict ratios/proportions of genotypes and phenotypes of offspring from the following cross, of a white-eyed male with wild type wings and a wild type red eyed female with wild type wings:  indicate sex of offspring along with phenotypes.

                                       XwY vg+ vg             x           Xw+Xw vg+vg
