What is the outcome of nondisjunction in meiosis I? a resultant gamete that is triploid a resultant gamete that may harbor from one chromosome both sister chromatids or none at all a resultant gamete that may harbor from one chromosome both homologs from one parent or none at all a resultant gamete that is devoid of all chromosomes

If nondisjunction occurs in meiosis I, what will be the result at the completion of meiosis? Select one: Two gametes will be n - 1; and two will be n. Two gamete will be n + 1; and two will be n - 1. One gamete will be n + 1; one will be n; and two will be n - 1. Two gametes will be n + 1; and two will be n. One gamete will be n + 1; one will be n - 1; and two will be n.

Consider a cell in which nondisjunction occurs for all chromosomes during meiosis I. What would be the result of this event? (A) two aneuploid gametes; each with an extra set of chromosomes (B) two haploid gametes and one aneuploid gamete with an extra set of chromosomes (C) four aneuploid gametes (D) four haploid gametes (E) two haploid gametes and two polyploid gametes.

If nondisjunction occurs during meiosis, only two gametes may form instead of four. Some gametes may have an extra copy of a chromosome. The gamete cannot join another to form an organism. The gametes redistribute chromosomes after meiosis.
