READ: A dominant characteristic tends to cancel a recessive characteristic, and it is clear that if the parents have different sets of dominant characteristics, then the offspring will have a combination of all the dominant characteristics of the parents. It follows therefore that the best offspring are those resulting from parents with different good dominant characteristics…..On the other hand, as unrelated people have more differences in characteristics, a marriage between such people would tend to produce ideal offspring with the good dominant characteristics of both parents, while the recessive characteristics are cancelled.
