Research Abstract

We analyzed and discussed sex-determining systems during vertebrate evolution, proposing a hypothesis that there might be a basic male sex-determining system driven by DMRT1 in non-mammalian vertebrates and that it might be changed into a SRY-SOX9 male sex-determining system during mammalian evolution. We also proposed a coevolution model of sex-determining genes and sex chromosomes, in which undifferentiated sex chromosomes easily allow replacement of a sex-determining gene with another new one, while specialized sex chromosomes are restricted a particular sex-determining gene.
