Abstract
We examined the sex determination of Eudromia elegans, which is a sexually monomorphic species, using a molecular biological technique. Based on the close relationship between tinamous and ratite birds, we performed nested-PCR using primers designed by Huynen et al. (2002) for sexing the ratite bird. As a result, a female specific DNA fragment whose size is about 350bp was amplified. This result indicates that the PCR method in this study is available for the sex determination of Eudoromia elegans.
