A comparative study of spermiogenesis in wild-type and T:t-bearing mice.
The results of a comparative ultrastructural study of spermiogenesis in T/tx, +/tx, +/T, C57BL/LJ, BALB/c and randomly breeding Swiss Albino mice are reported. The observations show that aberrant spermiogenesis occurs in males of all strains and genotypes and that the same specific types of abnormal spermatids are found in all of the males examined. No unique morphological defect which could be correlated with the increased transmission frequency of tx-bearing gametes can be found in males heterozygous for the tx allele.
