A balance in the number of chromosomes in humans is extremely important. If not, certain abnormalities may occur. Chromosomes carry our genetic material responsible for controlling body cells. An alteration in the number of chromosomes can significantly change our genetic structure.

In every normal human cell, there are 23 pairs of chromosomes (46 chromosomes in total). Alterations in this number can lead to abnormal growth and development. This process often takes place in reproductive cells formation, development of the fetus, or after birth.
