in Thomas Hunt Morgan's experiments examining the transmission of eye color in frut fies he observed that wnen he crossed hetersaygous red-eyed temales to redeyed maies 1/2 of the male offipring were whde-eyed while al of the female following best explains the results? 1/2 of the male offspring inherit a white-eye color alele from their heterozygous mothers Since there s no eye color gene on the Y chromosome their eyes are whte. 1/2 of the male offspring inherit a Y-chromosome from their fathers. Since there s no eye color gene on the Y chromosome, their eyes are white All of the female offspring inherit a dominant, red eyed alleie from their mothers A3 to 1 ratio of dominant to recessive offspring are expected in a single factor cross

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.
