THE GENETIC BASIS FOR DERYNI INHERITANCE: 1974

The primary genetic factor governing standard Deryni inheritance seems to be a simple sex-linked dominant carried on the X chromosome (designated X'). Thus, Deryniness per se is determined by the maternal line—not the paternal—and a male child displaying the Deryni capabilities must have had at least a heterozygous (X'X) Deryni mother.

X'X-XY

X'Y

Only one X' factor is necessary for the individual to display the full spectrum of Deryni capabilities; nor is there any appreciable difference between the power potentials of male and female, X'Y and X'X. One may readily see, however, that because of the double X configuration of the female, there is the possibility of an X'X' combination. This so-called “double-Deryni,” a homozygous Deryni female, is no more powerful than her heterozygous sisters, however, for the X' factor is not cumulative. The only advantage that a homozygous Deryni female would have over a heterozygous Deryni female is that all of her offspring would be Deryni—and even this is not a significant difference, since the prime factor appears to strengthen the X chromosome carrying it, so that a heterozygous Deryni female is likely to pass on the X' to her offspring rather than the X. (X' eggs are more hardy than X eggs, and more likely to be fertile.) This propensity of the X' chromosome to be passed on in preference to the X accounts, in part, for the survival of the Deryni through the great persecutions. Following are the probable outcomes of any Deryni mating, with non-Deryni offspring shown in brackets:
