Answers. Best Answer: Primary nondisjunction can happen during meiosis when the chromosomes fail to separate as they should. This produces gametes with more than or less than the usual number of chromosomes. Secondary nondisjunction happens during meiosis in an individual whose chromosomes are already the wrong number because of nondisjunction. So, primary nondisjunction could produce a gamete with two Xs and a zygote with XXY. When this person matures and produces gametes, secondary nondisj.
Trisomy. If a diploid cell undergoes meiosis and produces two gametes that are normal, and one with nâ 1 chromosomes, and one with n + 1 chromosomes, what type of error occurred? A nondisjunction error occurred in meiosis II, in which both sister chromatids of a chromosome migrated to the same pole of the cell.f a diploid cell undergoes meiosis and produces two gametes with n + 1 chromosomes and two gametes with nâ 1 chromosomes, what type of error occurred? A nondisjunction error occurred in meiosis I, in which both members of a homologous pair migrated to the same pole of the cell.
