netineya [11]

the phenomenon of the unequal separation in the meiosis is called as nondisjunction. If the nondisjunction causes the missing chromosome in a haploid gamete, the diploid zygote it forms with the another gamete will then contain only one of the copy of that chromosome from the other parent, this condition is known as monosomy.

The term "monosomy" is used to describe the absence of one of the member of the pair of chromosomes. Therefore, there are about 45 chromosomes in each cell of the body instead of that usual of 46.

Turner syndrome is the only and full monosomy that is seen in the humans — all other cases of the full monosomy are the lethal and the individual will not about survive development.
