An error in meiosis that produces a 47 XYY karyotype is best described by:
Meiosis division I of maternal oogenesis
Meiosis division II of maternal oogenesis
Meiosis division I of paternal spermatogenesis
Meiosis division II of paternal spermatogenesis
Only non-disjunction at paternal meiosis II produces a 24, YY gamete that yields a 47, XYY individual after fertilization.
