Curious zoologist American geneticist Thomas Hunt Morgan became a professor of zoology in 1904. Gregor Mendel had already shown how pea plants passed on different traits from one generation to the next. Morgan set out to see if this INHERITANCE pattern also occurred in animals. Morgan studied genes by breeding mutant white-eyed flies with normal red-eyed flies.
Thomas Hunt Morgan The scientist who researched the role of CHROMOSOMES in inheritance Flying high Morgan STUDIED FRUIT FLIES. He discovered that they passed on dominant and recessive genes to their offspring. He found that genes are arranged on chromosomes like beads on a string, and that some are always inherited together. Two red-eyed flies could still produce white-eyed male offspring if the female carried the recessive gene for white eyes. His breakthrough discovery won him the Nobel Prize in Medicine in 1933.
