| 摘 要： | 动物从受精卵发育到具有不同性别特征的个体是一个奇妙而又严谨的过程,是人类长期以来试图揭示的自然现象。上世纪90年代初在人类Y染色体上发现了性别决定基因SRY1],进而发现了一个新的Sox基因家族2]。上述基因的发现,促进了以哺乳类为代表的动物性别决定和分化机制研究。由于鱼类在脊椎动物中的特殊进化地位、庞大的种类数量以及显著的社会经济价值,鱼类的性别决定研究一直受到遗传和发育学者的重视。尽管离最终阐明鱼类性别决定的机制还有距离,但近20多年来鱼类性别决定的遗传基础研究已取得不少重要进展。本文试图根据现有文献资料,…

| Abstract: | As lower vertebrates, f ishes have complex modes of sex determination. From the cytogenet ic
perspective, only a small proportion of f ish species have heteromorphic sex chromosomes. At the present stage
sex determination can only be explained via .. genetics.. rather than .. genes.. in most species. Nevertheless, genes
associated with sex determination and male development were identified in a model fish medaka, Oryzias latipes.
Sequences or genetic markers specif ic to certain sex chromosomes were reported in some f ishes. These f indings
lay the groundwork for further studies on the function and regulat ion of sex genes aiming at elucidation of the
mechanism of sex determination, and provide potential tool for sexing f ish. In this mini..review , progress in the
past few decades in both cytogenetic and molecular genetic studies on sex determination of f ish were summarized.
Prospects, signif icance and possible future directions of the studies on fish sex determination were also discussed. |
