Meiotic H3K9me2 distribution patterns in csr-1, ekl-1, and drh-3 mutant males.

See Results and Figures 2 and 3 for descriptions and representative images of the three H3K9me2 distribution patterns (elevated, dispersed, and single focus). ��1 focus�� indicates that a single strong focus of H3K9me2 labeling was observed. N, number of nuclei counted.1These nuclei have recognizable pachytene morphology.2These abnormal nuclei are large and have a diffuse chromosomal morphology not typical of meiosis. The percent of nuclei within the pachytene zone with this morphology was: 10% for csr-1; 6% for ekl-1;him-8; and 4% for drh-3;him-8.
