Born 20 Jun 1875; died 3 Jan 1967 at age 91.

Reginald Crundall Punnett was an #English #geneticist who, with the English #biologist William Bateson, were among the first English #Mendelian geneticists.

They reported the discovery of two new #genetic principles: the first account of genetic #linkage in sweet pea; and gene interaction (1905). Punnett devised the #PunnettSquare to depict the #number and #variety of genetic #combinations.

Punnett had a role in connecting #Mendelism with #statistics. In 1908, Punnett was asked at a lecture to explain, “ if brown eyes were #dominant, then why wasn't the whole country becoming brown-eyed?” Punnett in turn asked his friend the mathematician, G. H. Hardy. Out of this conversation came the #Hardy-Weinberg Law which calculates how #population affects genetic #inheritance.
