Meiosis I. The diagram below shows how nondisjunction can take place during meiosis I if homologous don’t separate, and how this can lead to production of.
Nondisjunction during meiosis produces eggs or sperm cells that don’t have the normal number of chromosomes. In this lesson, learn about the.
Nondisjunction occurs in cell division when chromosomes do not divide properly. The diagram below shows nondisjunction taking place in mitosis.

During Mitosis. Somatic cells, or cells of the body, divide through mitosis.
From each original parent cell, two identical daughter cells are created. In the parent cell, each chromosome is composed of two identical sister chromatids.
During the anaphase stage, these chromatids normally separate, and one chromatid goes . When nondisjunction occurs, the sister chromatids fail to separate from each other in the anaphase and results in aneuploidy of cells―(2n + 1) in some and (2n – 1) in others.
This is also known as the chromatin or the anaphase bridge. Video: Nondisjunction in Meiosis: Definition & Examples Nondisjunction during meiosis produces eggs or sperm cells that don’t have the normal number of chromosomes.
The term nondisjunction during cell division refers to an abnormal anaphase in which either the homologous chromosomes from mother and father do not separate during meiosis 1 or the sister chromatids do not separate during meiosis 2. Nondisjunction means then no segregation of entire chromosomes or sister chromatids that will) Non-disjunction.
