We analyzed a number of genetic characteristics in androgenetic rainbow trout (Oncorhynchus mykiss) and their progeny. The androgenetic progeny of individual androgenetic males appeared genetically identical to each other based on eight enzyme loci. Their viability was no higher than that of androgenetic progeny of outbred males. Homozygous androgenetic female rainbow trout produced very poor quality eggs. When common eggs and sperm from outbred individuals were used to produce androgenetic and gynogenetic progeny, the yield of gynogenetic progeny was higher but some were heterozygous at protein loci, while no androgenetic progeny were heterozygous. Some androgenetic diploid rainbow trout were successfully produced from cryopreserved sperm. The progeny of some androgenetic males crossed to normal females were virtually all males, while the progeny of other males were virtually all females. This suggests that both XX and YY androgenetic individuals may develop as males. Androgenesis is likely to be useful for generating homozygous clones for research and for recovering strains from cryopreserved sperm.
我们分析了孤雄生殖虹鳟（Oncorhynchus mykiss）及其后代的一些遗传特征。基于八个酶位点，单个孤雄生殖雄性的孤雄生殖后代在基因上彼此相同。它们的活力不高于远交雄性的孤雄生殖后代。纯合孤雌生殖雌性虹鳟产生的卵质量很差。当使用远交个体的普通卵和精子来产生孤雄生殖和雌核生殖后代时，雌核生殖后代的产量更高，但有些在蛋白质位点是杂合的，而没有孤雄生殖后代是杂合的。一些孤雄生殖二倍体虹鳟是由冷冻保存的精子成功产生的。一些孤雄生殖雄性与正常雌性杂交的后代几乎全是雄性，而其他雄性的后代几乎全是雌性。这表明XX和YY孤雄生殖个体都可能发育为雄性。孤雄生殖可能有助于产生用于研究的纯合克隆，并从冷冻保存的精子中恢复品系。
