neoplasm

increased teratoma incidence ( J:19086 )

• high frequency of ovarian teratomas

reproductive system

abnormal female meiosis ( J:19086 )

• oocyte development failed to arrest during meiosis, leading to spontaneous parthenogenetic activation

female infertility ( J:19086 )

• 10 of 25 females tested were infertile

reduced female fertility ( J:19086 )

• females that are fertile have fewer and smaller litters compared with heterozygous females

decreased litter size ( J:19086 )

cellular

abnormal female meiosis ( J:19086 )

• oocyte development failed to arrest during meiosis, leading to spontaneous parthenogenetic activation
