reproductive system

reproductive system phenotype ( J:183982 )

N	• female fertility is normal

abnormal chiasmata formation ( J:183982 )

• small but significant increase in the frequency of univalent containing metaphase I oocytes

abnormal female meiosis ( J:183982 )

• small but significant increase in the frequency of univalent containing metaphase I oocytes

abnormal male meiosis ( J:183982 )

• slightly lower median foci numbers of RAD51, DMC1, and RPA in spermatocytes indicating a potential role in double strand break formation or repair
