Vedclass · Answer

(A) Thomas Hunt Morgan provided the experimental evidence that genes are located on chromosomes. Morgan studied the inheritance patterns of eye colour in the fruit fly, $Drosophila \, melanogaster$. He discovered that the gene for eye colour is located on the $X$ chromosome, which is a sex-linked trait. When he crossed a white-eyed male with a red-eyed female, the $F_1$ generation showed only red eyes, confirming that the trait followed the chromosomal inheritance pattern. This work linked the physical location of genes to specific chromosomes, thereby validating the Chromosomal Theory of Inheritance.
