一个新的性别决定基因DMY

DMY: a New Sex-determining Gene

虽然人们已经鉴定出了线虫、果蝇和哺乳动物的性别决定基因 ,但直到最近才首次在非哺乳类脊椎动物中发现了性别决定基因DMY .介绍了在青中发现DMY基因的经过 ,发现DMY基因的意义和DMY基因在其他鱼类中的分布 。

Sex-determining genes have been identified in flies, worms and mammals but not, until recently, in nonmammalian vertebrates. The characterization of DMY gene in medaka is introduced and the significance of this affair is discussed. Studies about the existence of this gene in other fish species are also been introduced. Finally, direction for future research is suggested.
