• although there are fewer than normal metaphase oocytes with normal chiasmata between homologous chromosomes, there is a 25% increase compared to mice with wild-type CHEK2

|
• P0 oocytes show asynapsis, but to a much less degree than in the presence of CHEK2 and a comparative 3 fold increase in dictyate oocytes

• although there is reduced fertility compared with C57BL/6J controls, compared with Prdm9 null mice wild-type for CHEK2 these double null females produce at least 1 litter in 6 months so have comparatively increased fertility, yet have a high rate of spontaneous abortion and perinatal deaths in pups.
