From the crossing of two demigods, a composite legacy emerges, that is, a demigod who inherits the skills and characteristics of both his grandfathers. However, one of the grandfathers has dominance over the other, so that he transfers more gifts and more of his characteristics to his grandson. Even so, the grandfather of the recessive genes also passes on genetic information to his grandson, but in smaller proportions and quantities.

Suppose a son of Zeus has a baby with Aphrodite's daughter. In this specific case, Zeus' genes dominate Aphrodite's. Thus, the son of the demigod couple will present a strong personality and exercise great control over the climate - Zeus' inheritance -, but at the same time, he will be beautiful and be able to seduce, with some effort, through his voice - Aphrodite's inheritance .
