Mybl1 mutant spermatocytes show minor synapsis defects of the XY pair and autosomal termini. (A-I) Surface spread spermatocyte nuclei were immunostained with the anti-SYCP3 and anti-SYCP1 antibodies, to detect AEs and CEs, respectively. CREST serum labels centromeres. The yellow double-headed arrow in B indicates the presumptive XY pair. White and yellow arrows in I indicate peri-centromeric and opposite end asynapsis, respectively. Genotypes are indicated, with a minus indicating the null allele.
