Fig. 2. — Failure of meiotic progression during prophase I in the mutant testis. A: Giemsa-stained preparation of testicular cell nuclei or chromosomes from 30-day-old wild-type rats indicating the presence of spermatocytes at zygotene (Zy), late zygotene or early pachytene (LZ/EP), midpachytene (MP), and metaphase I (MI) stages. B: Giemsa-stained preparation of testicular cell nuclei or chromosomes from 30-day-old homozygous mutant rats showing the presence of spermatocyte nuclei similar to control spermatocyte nuclei at zygotene (Zy) and late zygotene or early pachytene (LZ/EP) stages. Many degenerated nuclei were observed (asterisks), whereas no normal midpachytene nuclei were present. Scale bar: 50 µm.
