Gregor Johann Mendel

1822 - 1884

Gregor Mendel

Gregor Mendel is known as 'the Father of Modern Genetics' published his work, Versuche ├╝ber Pflanzenhybriden [Experiments on Plant Hybridization], on hereditary traits of peas, in 1866. The insight of his work became apparent later when the science of genetics confirmed his findings.

  • Moravian (German-speaking)

  • Subject
  • Biology, genetics

  • Fields
  • hereditary rules, meteorology

  • Laws
  • Law of Segregation

    Law of Independent Assortment (later known as Mendel's Laws of Inheritance)

  • Theories
  • 'Invisible factors' (today called genes) in hereditary can be of two types: dominant or recessive.

  • Experiments/Discoveries
  • Pea characteristics identified by cross-breeding, laying down the mathematical rules for the passing on of dominant and recessive genes in heredity.

Mendel studied 29,000 pea plant for seven characteristics: height, pod shape, pod colour, seed shape, seed colour, flower location and colour. He discovered that there were precise mathematical relationships: 25% of plants had recessive alleles, 50% were hybrid, 25% were purebred dominant.

Mendel's peas
Dominant and recessive genes produce offspring with characteristics 75% dominant gene and 25% recessive gene
