  • Underlined numbers on the left side of table show dramatic changes in telomere clustering in prophase I in normal meiosis. Underlined numbers on the right side of table show inhibition of meiotic telomere movement in pam1 meiocytes. L, leptotene; L-Z, leptotene-zygotene transition; Z, zygotene; Z-P, zygotene-pachytene; P, pachytene.
