Meiotic stages are shown for Scapa (2×, a–j) and Maris Peer (4×, k–t), including leptotene (a, k), zygotene (b, l), pachytene (c), late zygotene/pachytene-like (m), diplotene (d, n), diakinesis (e, o), metaphase I (f, p), anaphase I (g, q), metaphase II (h, r), anaphase II (i, s) and telophase II or tetrad stage (j, t).
