Spermatogenesis in Cancer productus Randall was studied to determine the availability of cells and chromosomes suitable for the localization of crab dAT. It was found that throughout most of the year the reproductive tract contained resting spermatogdnial cells and a few residual spermatophores. Between April and July there was a burst of meiotic activity observed both cytologically and by the incorporation of a radioactive DNA precursor, tritiated-thymidine.
The mean haploid chromosome number for C. productus was found to be 47.0 ± 4.1, lower than the previously reported number of 58. / Science, Faculty of / Zoology, Department of / Graduate
