In this study, cytogenetic analysis of an infertile mare revealed a 64, XY karyotype. The XY sex-reversed animal had a female phenotype with gonadal dysgenesis. Using Southern blot analysis, we tested for the presence of two Y-specific genes SRY and ZFY by using DNA isolated from peripheral blood leukocytes. The results showed that at least the DNA-binding domain of the SRY gene was deleted from the Y chromosome of the XY mare but that the ZFY gene was present on this chromosome.
在本研究中,对一匹不育母马的细胞遗传学分析显示其核型为64,XY。这只XY性反转动物具有雌性表型且伴有性腺发育不全。我们使用从外周血白细胞中分离的DNA,通过Southern印迹分析检测了两个Y特异性基因SRY和ZFY的存在情况。结果表明,XY母马的Y染色体上至少缺失了SRY基因的DNA结合结构域,但ZFY基因存在于该染色体上。
