| | Most trisomies are due to maternal non disjunction in meiosis I; monosomy X is frequently a consequence of non disjunction in male meiosis I. Tetraploidy (4n), is due to a post zygotic non disjunction in mitosis. | | | Numerical changes are to two types: polyploidy with changes in the number of sets of chromosomes (polyploidy) and aneuploidy with changes in the number of individual chromosomes (e.g., trisomies and monosomies). | | | These are small (unidentified) chromosomes with a centromere and may be of no consequence if they are "familial" but if they arise de novo in a fetus they may cause congenital anomalies. |

| | Turner Syndrome |
| | Therefore, there is a total of 45 chromosomes in each cell of the body, rather than 46. | | | Turner syndrome is a genetic disorder seen in girls that causes them to be shorter than others and to not mature sexually as they grow into adulthood. | | | About 50 percent of Turner syndrome results from full monosomy X. Forty percent of cases are "mosaic" which means these persons have some cells with a missing X chromosome and others with the normal number of chromosomes. |
