Gregor Mendel and Reginald Punnett

Reginald Punnett spent a large amount of time reading his father’s library on natural history, which sparked his interest and had a lasting impact on his career choices (Crew 1967). As Punnett continued his love for science, he eventually became one of the first scientists to study genetics at Cambridge University and helped to establish the field there.

Greg or Mendel discovered that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
