Nondisjunction event during meiosis
Nondisjunction is a
process whereby sister chromatid or homologous chromosomes failed to separate
during cell division. During meiosis, Nondisjunction produce eggs or sperms
cell that don’t have the normal number of chromosome. However, there are three
forms of Nondisjunction which were:
<span> a) Failure of sister chromatids to separate during
meiosis II</span>
b) Failure of a pair of homologous
chromosome to separate in meiosis I
c) Failure of sister
chromatids to separate during mitosis.
