人类的性别决定与先天性疾病

Sex Determination and Congenital Disease of Mankind

人类的性别是在性型结构和性基因数量的双重作用下由 ,有效数量大的X基因或Y基因决定性别 .各种性型的X基因与Y基因的有效数量的比率———性指数X/Y和Y/X :为 1.0时 ,发育为中性人 ;为 2 .0时 ,发良为正常女性和正常男性 ;为 3.0时 ,发育为超雌女性和超雄男性 .

The sex of mankind is determinated by significant amount Xgene or Ygene under the double effect between the structure of sexual type and the amount of sexual genes. If the rate (sex index X/Y and Y/X) of effecient amount between Xgene and Ygene in all kinds of sexual types is 1.0, it will develop into neuter man; if the rate is 2.0, it will develop into normal female and male; if the rate is 3.0, it will develop into superfemale and supermale.
