A technique of testicular homogenization and hemocytometric enumeration of elongated spermatids was applied to cockerels bearing Z-autosome translocations to estimate the effects of the translocations on sperm production. Testis weights, numbers of spermatids per gram of testis, and total number of spermatids were not significantly different between translocation-bearing cockerels and those of normal karyotype. In contrast to the adverse effects of X-autosome translocations on mammalian spermatogenesis, these data indicate that Z-autosome translocations do not quantitatively affect sperm production in cockerels.
将睾丸匀浆化和对延长型精子细胞进行血细胞计数的技术应用于携带Z-常染色体易位的公鸡，以评估易位对精子产生的影响。携带易位的公鸡与正常核型公鸡相比，睾丸重量、每克睾丸的精子细胞数量和精子细胞总数并无显著差异。与X-常染色体易位对哺乳动物精子发生的不利影响相反，这些数据表明Z-常染色体易位不会在数量上影响公鸡的精子产生。
