If nondisjunction occurs during meiosis,
◦ the resulting sex cells will be heterogametes.
◦ one-half of the resulting cells will exhibit trisomy and the other half monosomy.
◦ diploid cells will be produced.
◦ all gametes would lack a chromosome and these gametes would be infertile.
◦ none of the gametes will be capable of achieving fertilization.
