ObGyn 69, XXX Karyotype

A 26-year-old primigravida with no prior prenatal care presents at 13 weeks’ gestation with painless vaginal bleeding. Examination reveals a closed cervix. Fetal heart tones are not found, and ultrasound indicates an absence of fetal heart tones and a collapsed gestational sac. The woman is sent home with instructions to closely monitor, and the next day all products of conception are passed vaginally. Karyotyping of the material reveals a genotype of 69,XXX. Failure of what reproductive process likely contributed this genotypic abnormality?

Its an partial hydatidiform mole formed by fusion of 1 egg with 2 sperms. Actually after fusion of 1 sperm to egg the egg undergoes some confirmational change and doesn't allow penetrance of another sperm (Just don't remember the name of that stage exactly). So if egg does't undergo that confirmational change can lead to formation of partial mole.
