Classical genetics color, flower color and seed shape. Mendel took peas that had differing phenotypic characteristics and test-crossed them to assess how the parental plants passed the traits down to their offspring. He started by crossing a round, yellow and round, green pea and observed the resulting phenotypes. The results of this experiment allowed him to see which of these two traits was dominant and which was recessive based upon the number of offspring with each phenotype. Mendel then chose to further his experiments by crossing a pea plant homozygous dominant for round and yellow phenotypes with a pea plant that was

He was appointed a member of the Appeal Tribunal (a special court set up to reconsider a decision by another court) for the County of Berkshire in 1916. One of his friends was William Bateson (1861-1926), an advocate of the ideas of Gregor Mendel who introduced the term ‘genetics’ to describe the study of heredity and whose 1894 book Materials for the Study of Variation was one of the earliest formulations of the new approach to genetics. Sutton provided the means for Bateson to carry out extensive studies
