dKO-kls spermatocytes are proficient for sister chromatid cohesion. Hybridization of two DNA probes to the X and Y chromosomes renders a single dot signal for each probe in both wild-type and dKO-kls spermatocytes. Clear FISH signals for both probes can be observed in 63% of the 90 leptonema-like cells analyzed. Bar, 100 µm.
