%X Sex determination is a complex regulatory process of early embryogenesis.Embryo must make a developmental decision to develop as a male or female during gonadogenesis.This paper reviews genetic systems of sex determination,gonadogenesis,key genes involved in sex determination of vertebrates.Molecular evolution processes of sex chromosomes and sex determination provide a clue to tendency of sex-determining genes to appear on heterotypic sex chromosome.
