Sex-Linked Inheritance Problem Set 2
Problem 2: Predicting the genotype of a male fly
Correct!
The alleles for eye color and for body color are on the X chromosome of Drosophila, but not on the Y. Red eye color (w+) is dominant to white eye color (w), and tan body color (y+ ) is dominant to yellow body color (y).What is the genotype of a tan-bodied, white-eyed male?
A.
B.
The male is hemizygous for both the recessive (white) eye color allele and dominant (tan) body color allele.
His genotype is Xwy+ Y.C.
