Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid cell. It consists of two stages: meiosis I and meiosis II.
In meiosis I, homologous chromosomes are separated, resulting in two haploid cells, each with half the number of chromosomes as the original diploid cell. These cells are normally haploid with a normal number of chromosomes.
Nondisjunction is an error in cell division where chromosomes do not separate properly. If nondisjunction occurs during meiosis II, it affects the separation of sister chromatids.
When nondisjunction occurs in meiosis II, it results in some gametes having an abnormal number of chromosomes. Specifically, some cells may have an extra chromosome (n+1) or be missing a chromosome (n-1).
Therefore, at the end of meiosis I, the cells are haploid with a normal number of chromosomes, but after meiosis II with nondisjunction, the resulting cells are haploid with an abnormal number of chromosomes.
