Detailed explanation-1: -Monosomy, or the loss of one chromosome in cells, is another kind of aneuploidy. “Mono-” is Greek for “one"; people with monosomy have one copy of a particular chromosome in cells instead of the normal two copies. Turner syndrome (also known as monosomy X) is a condition caused by monosomy .

Detailed explanation-2: -What are monosomies? The term “monosomy” is used to describe the absence of one member of a pair of chromosomes. Therefore, there are 45 chromosomes in each cell of the body instead of the usual 46.

Detailed explanation-3: -What is the difference between trisomy and monosomy? Trisomy disorders occur when you have an extra copy of a chromosome. Monosomy occurs when you are missing a copy of a chromosome. Both of these genetic conditions are the result of a genetic mutation where your cells don’t divide as they should.

Detailed explanation-4: -Human monosomy Turner syndrome – People with Turner syndrome typically have one X chromosome instead of the usual two X chromosomes. Turner syndrome is the only full monosomy that is seen in humans-all other cases of full monosomy are lethal and the individual will not survive development.

Detailed explanation-5: -There are two main types of aneuploidy; there can be an extra copy of a chromosome (trisomy) or a missing copy of a chromosome (monosomy).
