If the sex-reversal factor (Sxr) in mice is represented by a segment of the Y chromosome translocated on to an autosome, this segment might be expected to show some evidence of attempted pairing with the normal Y chromosome at the first meiotic division. Our failure to find such evidence in a light microscope study of the silver-stained pachytene spermatocytes from Sxr/4, XY males further supports existing cytological information that the factor is more likely to be represented by an autosomal dominant gene mutation.
如果小鼠中的性别反转因子（Sxr）由一段易位到常染色体上的Y染色体片段所代表，那么在第一次减数分裂时，这段片段可能会显示出与正常Y染色体试图配对的一些证据。我们在对Sxr/4、XY雄性小鼠的银染粗线期精母细胞进行光学显微镜研究时未能找到此类证据，这进一步支持了现有的细胞学信息，即该因子更可能由常染色体显性基因突变所代表。
