Thomas Hunt Morgan discovered mutation of white$-$eyed in fruitfly and was awarded Noble prize for this in $1933$. Normally these flies have red colour eyes but he noticed that few male flies have white colour eyes. He immediately crossed these flies with wild flies i.e., red$-$eyed flies and observed that the $F_1$ generation has only red-eyed flies but when he selfed these flies he saw the ratio is $3 : 1$.
