Question
In Thomas Hunt Morgan's experiments examining the transmission of eye color in fruit-flies, he observed that when he crossed heterozyYgous red-eyed females to red-eyed males, 1/2 of the male offspring were white-eyed, while all of the female offspring are red-eved, Which of the following best explains the results? 1/2 of the male offspring inherit a white-eye color allele from their heterozygous mothers. Since there is no eye color gene on the Y chromosome, their eyes are white. 1/2 of the male offspring inherit a Y-chromosome from their fathers. Since there is no eye color gene on the Y chromosome, their eyes are white. All of the female offspring inherit a dominant, red-eyed allele from their mothers A 3 to 1 ratio of dominant to recessive offspring are expected in a single factor cross

Expert Solution
Step 1

A sex-linked trait is a trait where the expression of a gene present on the sex-chromosome (either X or Y, in mammals) depends upon the sex of the particular individual. Eye color of fruit fly, Drosophila, is one such trait, which was identified by famous biologist, T.H. Morgan in 1910.
