We seek to develop a plausible conception of genetic parenthood, taking a recent discussion by Heidi Mertes as our point of departure. Mertes considers two conceptions of genetic parenthood-one invoking genetic resemblance and the other genetic inheritance-and presents counter-examples to both conceptions. We revise Mertes' second conception so as to avoid these and related counter-examples.
