The present invention provides a perennial lineage engendered with hyperdominant traits that express consistent penetrance in all descendants of a founder organism. A genetic construct containing one or more genetic elements encoding a self-regulating feedback loop generates a regulatory RNA, polypeptide, or other gene product at or below a trigger level of concentration in a zygote and indicates with respect to the concentration level whether one or two copies of a genetic construct conferring a hyperdominant trait exist in said zygote.
