In this episode of pplpod, we dig into the life of Gregor Mendel, the 19th-century Augustinian friar who escaped a life of farming to become the posthumous "father of modern genetics". We explore how Mendel utilized the 2-hectare experimental garden of St. Thomas' Abbey to cultivate some 28,000 plants—mostly peas—identifying the "invisible factors" we now recognize as genes.
Join us as we discuss:
• The Struggle: How Mendel joined the monastery to avoid "perpetual anxiety" about money, only to fail the oral portion of his teacher certification exams twice.
• The Discovery: His formulation of the Law of Segregation and the Law of Independent Assortment, based on observing dominant and recessive traits like plant height and seed shape.
• The Silence: Why his seminal 1866 paper was completely ignored by contemporaries—including Charles Darwin—until its dramatic rediscovery in 1900 by scientists like Hugo de Vries and Carl Correns.
• The Controversy: The Mendelian Paradox, sparked in 1936 when statistician R.A. Fisher argued that Mendel’s data ratios were "implausibly" close to expectations, leading to accusations that the data may have been "cooked" or falsified.
• The Bees: Mendel’s less successful experiments breeding aggressive Cyprian and Carniolan bees, which annoyed his fellow monks and visitors.
From his physics studies under Christian Doppler to the identification of the final Mendel pea genes in 2025, this episode covers the full scope of a humble genius who predicted, "My time will come".
