What are monosomies? The term "monosomy" is used to describe the absence of one member of a pair of chromosomes. Therefore, there is a total of 45 chromosomes in each cell of the body, rather than 46.
Monosomy - an overview | ScienceDirect Topics
Monosomy (the lack of one member of a chromosome pair) and trisomy (a triplet instead of the normal chromosome pair) are typically the result of nondisjunction during meiosis. When this happens, one gamete shows monosomy, and the other shows trisomy of the same chromosome.
