In Drosophila , a Narrow, Reduced Eye Is Called a Bar-Eye

Short Answer

In Drosophila , a narrow, reduced eye is called a bar-eye. It is due to a dominant X-linked allele ( B ), while the full wild-type is due to the recessive gene ( B+ ). Give the F ₁ and F ₂ genotypic and phenotypic expectations of a cross of a homozygous wild-type female with a bar-eyed male.
