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 F1 and F2 genotypic and
  phenotypic expectations of a cross of a homozygous wild-type female with a bar-eyed male. What will be an ideal response?
 
 

Question 2

In humans, an X-linked disorder called coloboma iridia (a fissure in the iris) is a recessive trait. A
  normal couple has an afflicted daughter. The husband sues the wife for divorce on the grounds of
  infidelity. Would you vote in his favor? What will be an ideal response?
