  • The first successful scientific study on inheritance was carried out in an Austrian monastery garden in the mid 19th Century. It was discovered by Gregor Mendel and he used pea plants to study the inheritance of characteristics such as flower colour, seed shape and plant height.
  • Pea plants carry the same phenotypic features and are controlled by a single gene with two alternative alleles.
  • Mendel could control his experiments by ‘pure-breeding’ plants by transferring pollen by hand.
