A trisomy and a monosomy are types of numerical chromosome abnormalities that can cause certain birth defects. Normally, people are born with 23 chromosome pairs, or 46 chromosomes, in each cell â one inherited from the mother and one from the father.
Human conditions due to monosomy: 1  Turner syndrome â Women with Turner syndrome typically have one X chromosome instead of the usual two sex chromosomes. 2  Turner syndrome is the only full monosomy that is seen in humansâall other cases of full monosomy are lethal and the individual will not survive development.
