... We have found that if we cross two F1 hybrids we can predict or expect their offspring (F2) will be in the ratio of 3 dominant characteristic to 1 recessive characteristic. However when we actually carry out these crosses, the predicted numbers rarely occur. eg if there are 100 F2 pea plants we woul ...
