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]
The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 [5] and 1903, [6] as well as to independent work by Theodor Boveri during roughly the same period. [7] Boveri was studying sea urchins, in which he found that all the chromosomes had to be present for proper embryonic development to take place. [8]

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 (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.
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 ...
