A recessive allele causes Drosophila to have white eyes instead of wild-type eyes. This eye colour gene is known to be X-linked. In a cross between homozygous wild-type females and white-eyed males, all F1 progeny have wild-type eyes. What ratio of wild-type to white-eyed progeny can be expected in each sex if F1 females are crossed to males of the same genotype as their father? a. Males – 1 : 0; females – 1 : 0 b. Males – 1 : 1; females – 1 : 0 c. Males – 0 : 1; females – 1 : 1 d. Males – 1 : 1; females – 1 : 1

Question
A recessive allele causes Drosophila to have white eyes instead of wild-type eyes. This eye colour
gene is known to be X-linked. In a cross between homozygous wild-type females and white-eyed
males, all F1 progeny have wild-type eyes.
What ratio of wild-type to white-eyed progeny can be expected in each sex if F1 females are
crossed to males of the same genotype as their father?
a. Males – 1 : 0; females – 1 : 0
b. Males – 1 : 1; females – 1 : 0
c. Males – 0 : 1; females – 1 : 1
d. Males – 1 : 1; females – 1 : 1
