WebMay 16, 2024 · After DNA replication in the parent cell, each chromosome is composed of two identical sister chromatids. During the anaphase stage of mitosis, these chromatids separate, and one chromatid goes into each daughter cell. However, when nondisjunction occurs, the chromatids do not separate. WebNondisjunction can occur during either meiosis I or meiosis II. If nondisjunction occurs during meiosis I, then all of the resulting gametes will have an abnormal number of chromosomes (one gamete will have an extra chromosome and the other will be missing a …

WebFeb 21, 2024 · Sister chromatids are identical copies of a single chromosome that are produced during the process of DNA replication, which occurs prior to cell division. Each chromosome consists of two identical sister chromatids that are held together by a protein complex called the centromere. WebThe centromere links a pair of sister chromatids together during cell division. This constricted region of chromosome connects the sister chromatids, creating a short arm (p) and a long arm (q) on the chromatids.
