21 Facts About Alfred Sturtevant

Alfred Henry Sturtevant was an American geneticist.

Alfred Sturtevant's grandfather Julian Monson Sturtevant, a Yale University graduate, was a founding professor and second president of Illinois College, where his father taught mathematics.

Alfred Sturtevant attended a one-room schoolhouse until entering high school in Mobile.

Alfred Sturtevant further pursued his interest in genetics under Thomas Hunt Morgan, who encouraged him to publish a paper of his pedigrees shown through Mendelian genetics.

Alfred Sturtevant joined Morgan's research team in the "fly room", in which huge advances were being made in the study of genetics through studies of the fruit fly Drosophila.

Alfred Sturtevant warned the public of possible harmful genetic effects of nuclear fallout despite supposedly low levels of ionizing radiation.

Alfred Sturtevant postulated that genes that remained together while being passed from generation to generation must be located on the same chromosome.

Alfred Sturtevant showed that the gene for any specific trait was in a fixed location.

Alfred Sturtevant's experiments determined that the frequency of double crossing over can be used to deduce gene order.

Alfred Sturtevant demonstrated this concept by constructing crosses of three segregating genes, called "three-factor crosses".

Alfred Sturtevant found that using three genes as opposed to two provided most accurate information about gene order on chromosome.

Alfred Sturtevant surmised that unequal crossing-over was possibly a main force of evolution.
