For the analysis of meiotic cells, the testicular follicles were processed by using the squash technique and then stained according to the conventional Feulgen method
by using Schiff reactive after an acid hydrolysis with 1N HCL (hydrochloric acid) at 65[degrees]C for 25min (Feulgen & Rosenbech 1924).
