This fact helped him a lot in his experiments. He worked in the garden of the monastery so he decided to study the genetics of peas.

Mendel performed dihybrid crosses in plants that were true-breeding for two traits: A plant with round and yellow seeds was crossed with a plant that had wrinkled and green seeds.
The traits for round seed (RR) and yellow seed (YY) are dominant. Wrinkled seed (rr) and green seed (yy) are recessive. The resulting generation (F1) were all heterozygous for round and yellow seeds (RrYy).

About 9/16 of the F2 plants had round, yellow seeds; 3/16 had round, green seeds; 3/16 had wrinkled, yellow seeds; and 1/16 had wrinkled, green seeds.
