Immunocytological evidence that SYCP3 deficiency increases DSB repair in Dmc1 null oocytes. Plotted are numbers of foci/oocyte for the indicated markers (RAD51 or RPA) in surface-spread chromosomes of newborn oocytes. Each represents a single oocyte. The indicated number of oocytes were scored, and these oocytes were obtained from three pups/genotype. Black horizontal lines in the graph indicate median values. Asterisks represent the significance levels (by Mann–Whitney test): ***P = 0.0004; ****P < 0.0001.
