Fig. 8. PPH-4.1 may be involved in chiasma formation during meiotic prophase I. (A,B) Oocytes in adult hermaphrodite gonads were stained with DAPI. The distal end is to the left. (A) Wild-type oocytes at the diakinesis stage contain six bivalent chromosomes. (B) In a pph-4.1(RNAi) gonad, oocytes in the distal region contain six bivalents, but oocytes in the proximal region contain twelve univalent chromosomes. (C,D) Magnified view of the indicated areas in (A) and (B), respectively. (A,B) Bar, 10 µm. (C,D) Bar, 2 µm.
