"Nondisjuction in Meiosis," a piece to accompany an article in Scientific Slug, the UCSC Scientific magazine

Nondisjuction
Chromosomes fail to separate during meiosis
There are 3 types of Down Syndrome
a)Trisomy 21: In most cases (95%), all the body cells of the patient have three chromosomes 21, which happens due to the meiosis non-disjunction.
b)Mosaic Down Syndrome: Only some body cells have an extra chromosome 21 (non disjunction in mitosis).
c)Translocation Down Syndrome: In this case, a part of chromosome 21 is attached to another chromosome. So the patients have 2 chromosomes 21 plus a part of a third chromosome 21.
