Heredity particulate inheritance of genes can be attributed to the Moravian monk Gregor Mendel who published his work on pea plants in 1865. However, his work was not widely known and was rediscovered in 1901. It was initially assumed that Mendelian inheritance only accounted for large (qualitative) differences, such as those seen by Mendel in his pea plants—and the idea of additive effect of (quantitative) genes was not realised until R. A. Fisher's (1918) paper, "The Correlation Between Relatives on the Supposition of Mendelian Inheritance" Mendel's overall contribution gave scientists a useful overview that traits were inheritable.

Muriel Wheldale Onslow teachings. In 1900 she entered Newham College, Cambridge and took a class in Natural Sciences Tripos. In 1903 she joined William Bateson's genetics lab at Cambridge where she began her study focusing on the interaction of factors and of the inheritance of petal color in Antirrhinum (snapdragons). William Bateson was the English biologist who was the first person to use the term genetics to describe the study of heredity, and the chief populariser of the ideas of Gregor Mendel following their rediscovery in 1900. Bateson and Onslow carried out a series of breeding experiments in various plant and animal species
