Johann Gregor Mendel – Father of Genetics:

gregor mendel

Johann Gregor Mendel (1822–1884) was an Austrian monk, often regarded as the “father of genetics”, whose studies of the inheritance of traits in pea plants helped to lay the foundation for the later development of the field of genetics. His studies showed that there was particulate inheritance of traits according to basic laws of inheritance.

Gregor Mendel chose pea plants for his experiments for the following reasons:

  • Presence of observable traits with contrasting forms: some plants were tall others short, some flowers were white others red, some seeds were round others wrinkled, etc.
  • It produces many offspring in one cross.
  • Short life cycle (annual plants).
  • He could pollinate them himself since peas are usually self-pollinating.
