Alfred Henry Sturtevant (1891?1970)

Alfred Henry Sturtevant studied heredity in fruit flies in the US throughout the twentieth century. From 1910 to 1928, Sturtevant worked in Thomas Hunt Morgan?s research lab in New York City, New York. Sturtevant, Morgan, and other researchers established that chromosomes play a role in the inheritance of traits. In 1913, as an undergraduate, Sturtevant created one of the earliest genetic maps ...

"The linear arrangement of six sex-linked factors in drosophila, as shown by their mode of association? (1913), by Alfred Henry Sturtevant

In 1913, Alfred Henry Sturtevant published the results of experiments in which he showed how genes [4] are arranged along a chromosome. Sturtevant performed those experiments as an undergraduate at Columbia University [5], in New York, New York, under the guidance of Nobel laureate Thomas Hunt Morgan [6]. Sturtevant studied heredity using Drosophila [7], the common fruit fly. In his experiments...

Alfred Henry Sturtevant and crosses between Drosophila melanogaster and Drosophila simulans.

W HEN SEWALL WRIGHT wrote a recommendation for H. J. MULLER in the late 1930s, he described MULLER as perhaps the greatest living geneticist. WRIGHT later expressed this evaluation in conversation on many occasions. But when it came to the relationships among genetics, evolution and systematics, WRIGHT’S clear candidate for honors in the MORGAN group was A. H. STURTEVANT. From his student days ...

Early Life and Education

Linked Genes May Be Mapped by Three-factor Test Crosses

In studying within-chromosome recombination, Morgan proposed that the farther apart two genes were located on a chromosome, the more likely they would be to exhibit crossing-over. Alfred Sturtevant took this argument one step further and proposed that the probability of a cross-over occurring between two genes could be used as a measure of the chromosomal distances separating them. While this s...
