Thomas Hunt Morgan(1866-1945)

American geneticist Thomas hunt Morgan studies at Johns Hopkins University. Morgan's interest turned from embryology to the mechanism involved in heredity. Morgan found that the rapidly multiplying Drosophila, the fruit fly, for studying how specific traits are transmitted through generations. Charting the family trees of fruit flies with such mutations as stunted wings, asymmetric bodies, and mismatched eye colouring, following rediscovery of Austrian scientist Gregor Mendel's work. Morgan elaborated the details of inheritance. he realised that there were more genes than chromosomes in Drosophila. he also discovered sex chormoses and inented the techniques of genetic mapping. Thanx largely to Morgan's book, The Theory of the Gene (1926), genetics was accepted as a legitimate branch of biology. he was awarded noble Prise for Physiology and medicine in 1933
