Thomas Hunt Morgan (September 25, 1866 – December 4, 1945) [2] was an American evolutionary biologist, geneticist, embryologist, and science author who won the Nobel Prize in Physiology or Medicine in 1933 for discoveries elucidating the role that the chromosome plays in heredity.
Alfred Henry Sturtevant (November 21, 1891 – April 5, 1970) was an American geneticist.Sturtevant constructed the first genetic map of a chromosome in 1911. Throughout his career he worked on the organism Drosophila melanogaster with Thomas Hunt Morgan. [2]
Édouard-Gérard Balbiani (1823–1899), French embryologist who found chromosome puffs now called Balbiani rings; David Baltimore (born 1938), US biologist, Nobel Prize for the discovery of reverse transcriptase; Guido Barbujani (born 1955), Italian population geneticist and evolutionary biologist
Police used genome sequencing to identify a body found in the Mississippi River more than four decades ago as a 15-year-old girl from Iowa.
TROY, Mo. (AP) — Forty-six years after a Missouri hunter found a body in the Mississippi River, the victim has been identified as a 15-year-old girl from Iowa.
Thomas Hunt Morgan discovered sex linked inheritance of the white eyed mutation in the fruit fly Drosophila in 1910, implying the gene was on the sex chromosome. In 1910, Thomas Hunt Morgan showed that genes reside on specific chromosomes. He later showed that genes occupy specific locations on the chromosome.
With the newly discovered genetic information found in the skin samples, the researchers were able to determine for the first time that the woolly mammoth had 28 pairs of chromosomes, just like ...
The Dutch sprinter Foekje Dillema was expelled from the 1950 national team after she refused a mandatory sex test in July 1950; later investigations revealed a Y-chromosome in her body cells, and the analysis showed that she was probably a 46,XX/46,XY mosaic female. [7] In 1953, a human chimera was reported in the British Medical Journal. A ...
