Fertilized poultry embryos are treated with estrogens or antiandrogens or estrogens in combination with antiandrogens during a period of embryonic development when the gonads are bipotential. This treatment causes genetic males to exhibit a female phenotype. When sex reversed male birds are crossed with normal male birds all offspring will be genotypically male.
受精的家禽胚胎在胚胎发育期间,性腺处于双潜能期,此时使用雌激素或抗雄激素,或雌激素与抗雄激素联合使用。这种处理方法会使遗传雄性表现出雌性表型。当性别逆转的雄性鸟类与正常雄性鸟类杂交时,所有后代的基因型都是雄性。
