Thomas Hunt Morgan (1866-1945), an American genetics and Nobel Prize winner of 1933, is considered as Father of Experimental Genetics for his work on and discovery of linkage, crossing over, sex linkage, criss cross inheritance, linkage maps, mutability of genes, etc. He is called fly man of genetics because of selecting fruit fly (Drosophila melanogaster) as research material in experimental genetics. It was largely due to his book, “The Theory of Gene”, that genetics was accepted as a distinct branch of biology.
