2018-02-09 · What is Aneuploidy. Aneuploidy refers to a condition in which one or a few chromosomes are added or deleted from the normal chromosome number. Hence, the number of chromosomes in aneuploidy can be greater or smaller than the number of chromosomes in the wild type, a strain that prevails among individuals in natural conditions.

Aneuploidy, the occurrence of cells with more or less than the correct (euploid) complement of chromosomes, is especially common. The frequency of aneuploid cells in human females increases from 3 percent at age 10 to 13 percent at age 70. Aneuploidy is a condition in which a cell has an incorrect number of chromosomes. Aneuploidies are a common cause of miscarriage, especially in early pregnancy.
