从游泳期开始连续三个月的饮食中服用不同的雌激素，导致雌性数量超过雌性，其余的处理组由雄性和两性组成。成熟的两性人自交或与标准的雄性和雌性交配。这些雌雄同体和一些雌雄同体被证明是遗传雄性；从它们的卵子中获得雄性的频率平均为76.6%，这表明YY基因是可行的。当这些后代与标准雌性交配时，这些后代中的九个雄性中有四个提供了所有的雄性后代。
Dietary administration of various estrogens for three months from swim-up stage resulted in excess of females, the remainder of the treated group consisting of males and hermaphrodites. Mature hermaphrodites were self-fertilized or mated with standard males and females. Thes hermaphrodites and some of the estrogen-treated females proved to be genetic males; the frequencies of males obtained from their ova averaged 76.6%, suggesting viability of the YY genotype. Four of nine tested males of those progenies provided all male offspring when mated with standard females.
