What happened when Mendel crossed the members of the seven different types of F1 generation of peas with the other F1 peas that shared the same characters? What is the ratio of dominant to recessive characters that appeared in the F2 generation?
In the second ("F2") generation of peas that resulted, three quarters of the peas showed the dominant forms of their F1 generation parents while one quarter showed the recessive forms that had not been expressed since the original P generation. For example, crossing the peas with green pods from the F1 generation resulted in a F2 generation in which three quarters had green pods and one quarter had yellow pods.
