The cytogenetic study performed has shown that karyotyping of meiotic cells can be based on the synaptonemal complexes (SC) of spreading pachytene spermatocytes of bull and of horse. The horse SC karyotype has not been previously described. A comparison of the relative length of SC with metaphase chromosomes of bull and horse somatic cells has revealed the correspondence of the chromosome length in pachytene of meiosis and metaphase, which is in agreement with the data on house mouse and Chinese hamster. The method of spreading pachytene cells may be of great practical importance in studies of the fertility disturbances in farm animals.
所进行的细胞遗传学研究表明，减数分裂细胞的核型分析可以基于公牛和马的粗线期精母细胞铺展后的联会复合体（SC）。此前尚未描述过马的SC核型。将公牛和马体细胞的SC相对长度与中期染色体进行比较，结果显示减数分裂粗线期和中期的染色体长度相对应，这与家鼠和中国仓鼠的数据一致。铺展粗线期细胞的方法在研究家畜繁殖障碍方面可能具有重要的实际意义。
