On the Relations Between Compositional and Evolutionary Theories
Segregation, according to which, in such matings, the members of each pair in one parent separate to unite with a member of the corresponding pair from the other parent; if the parents each have a dominant (A) and a recessive (a) factor of the pair, the offspring may be either AA, Aa, aA, or aa; and those alternatives are equiprobable, so that the observed ratios of dominant to recessive character in the offspring of hybrids will be 3:1.
Independent assortment, according to which any pair of elements does not affect the equiprobability of alternative combinations of any other pair.
