If two parents, both homozygous but for different characters, are crossed, the offspring will all be hybrid and will exhibit the character which is dominant. In crossing these hybrid or heterozygous individuals it is clear that different genes may be distributed to the different sex cells which the individuals develop and that thus when these unite with other cells, varying combinations of genes will occur.

In crossing these hybrid or heterozygous individuals it is clear that different genes may be distributed to the different sex cells which the individuals develop and that thus when these unite with other cells, varying combinations of genes will occur. For instance, considering only one pair of genes, if the dominant gene received from one parent is indicated by A and the recessive gene received from the other parent, by a, some of the sex cells will possess A and others a.
