Describe the features of G. Mendel’s work that allowed him to achieve success.

1) Different varieties of seed peas, which gave fertile offspring during intraspecific crosses
2) Peas are a self-pollinating plant
3) Peas are unpretentious and have high fertility
4) As experimental traits Mendel chose simple qualitative alternative traits of the “either-or” type (flowers are purple or white, seeds are yellow or green)
5) When processing the received data, Mendel kept a strict mathematical account of the phenotypes of all plants and seeds
