Gregor Mendel

  1. Gregor Johann Mendel was a German-speaking Moravian scientist and Augustinian friar who gained posthumous fame as the founder of the modern science of genetics.
  2. Born: July 20, 1822, Hynčice, Czech Republic
  3. Died: January 6, 1884, Brno, Czech Republic
  4. Full name: Gregor Johann Mendel
  5. Education: Palacký University, Olomouc (1840–1843), University of Vienna
  6. Siblings: Veronica Mendel, Theresia Mendel
  7. Parents: Rosine Mendel, Anton Mendel
  8. He profound significance of Mendel's work was not recognized until the turn of the 20th century (more than three decades later) with the independent rediscovery of these laws.[3] Erich von Tschermak, Hugo de Vries, Carl Correns, and William Jasper Spillmanindependently verified several of Mendel's experimental findings, ushering in the modern age of genetics.

Reginald Punnett

  1. Reginald Crundall Punnett FRS was a British geneticist who co-founded, with William Bateson, the Journal of Genetics in 1910.
  2. Born: June 20, 1875, Tonbridge, United Kingdom
  3. Died: January 3, 1967, Old Cleeve, United Kingdom
  4. Books: Mimicry in Butterflies, Mendelism
  5. Education: Clifton College, Gonville and Caius College, Cambridge,University of Cambridge
  6. During World War I, Punnett successfully applied his expertise to the problem of the early determination of sex in chickens. Since only females were used for egg-production, early identification of male chicks, which were destroyed or separated for fattening, meant that limited animal-feed and other resources could be used more efficiently. Punnett's work in this area was summarized in Heredity in Poultry (1923). With Michael Pease as his assistant, he created the first auto-sexing chicken breed, the Cambar, by transferring the barring gene of the Barred Rock to the Golden Campine.
