Mendels second experiment

gregor mendel

mendel allowed the first generation from each of the 7 crosses to self-pollinate. this time the plant with the dominate trait for seeds shape (which is round) was allowed to self pollinate. medel preformed this same experiment on the two traits of each of the seven characteristics. no matter which characteristic mendel investigated, when the first generation was allowed to self-pollinate, the recessive trait reappeared.
