(1 point) Nondisjunction can result in gametes that carry an extra copy of a chromosome, and at fertilization this can result in a zygote with a trisomy. In some cases, the zygote somehow eliminates one of the three copies of the trisomic chromosome, restoring euploidy. It's really not understood how this happens.
