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.
Numerical abnormalities (aneuploidy from GHR,) can occur with either the autosomes or the sex chromosomes. Monosomy is the absence of a chromosomal region or entire chromosome resulting in only one copy of the genetic material.ex chromosome Aneuploidy: Turner syndrome (45,X). Turner syndrome (45,X) is caused by complete or partial absence of the second sex chromosome. Approximately 50% have complete loss of the second sex chromosome.
