| Research Abstract |
We have cloned vasa, 52Sp50, cyp19a, dmrt1, foxl2 gene from Hon-moroko(Gnathopogon caerulescens). The expression level of 42Sp50 gene, which are know as an oocytes specific gene, gradually increased as sex-differentiation process was advanced and significantly differed among individuals. From these facts, we recognized that the 42Sp50 gene was a good indicator for female and that the individuals expressing 42Sp50 gene must be female.
