Sturtevant, Alfred Henry

 

Born Nov. 21, 1891, in Jacksonville, 111.; died Apr. 6, 1970, in Pasadena, Calif. American geneticist. Member of the National Academy of Sciences of the USA.

Sturtevant graduated from Columbia University in 1912. He was a professor at the California Institute of Technology from 1928 to 1962. From 1911 he worked in T. H. Morgan’s laboratory, where he made an important contribution to the development of the chromosome theory of heredity. In 1913, he was the first to substantiate the theory of the linear arrangement of genes in chromosomes, suggesting that genes be mapped according to their frequency of crossing-over. Sturtevant discovered the phenomenon of suppression in 1920 and the gene position effect in 1925. In 1926 he determined that chromosomal parts are subject to inversion and studied the effect of chromosomal parts on crossing-over. Sturtevant’s works dealt with the systematics and comparative cytogenetics of various species of the genus Drosophila.

He shows how Charles Darwin's observations of inherited traits became the base from which a host of successors, such as William Bateson, Walter Sutton, Alfred Sturtevant, Calvin Bridges, Herman Muller, James Watson, and Francis Crick.
The first such map was developed in 1913 by Alfred Sturtevant while he was an undergraduate in zoology at New York's Columbia University.
The invention of linkage mapping in 1912 - largely the inspiration of graduate students Alfred Sturtevant and Calvin Bridges, according to Kohler - rapidly obliged the Drosophilists to "standardize" the fly, that is to remove all unwanted genetic variation and to create an instrument for the recombinant mapping of the genome.
