Chromosome abnormalities usually happen as a result of an error in cell division. Meiosis is the name used to describe the cell division that the egg and sperm undergo when they are developing. Normally, meiosis causes a halving of chromosome material, so that each parent gives 23 chromosomes to a pregnancy.
Meiotic Nondisjunction (abnormal meiosis) 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. always result in daughter cells with abnormal number of chromosomes.
