Aneuploidy refers to an abnormal number of chromosomes in a cell, which can either be an excess or a deficiency of chromosomes. The two main categories of aneuploidy are autosomal aneuploidies and sex chromosome aneuploidies, based on the type of chromosomes affected. Autosomal chromosomes are the 22 pairs of chromosomes that are not involved in determining an individual’s sex, while sex chromosomes determine an individual’s biological sex (XX for females, XY for males).
