monosomy
A cellwith two of each kind of chromosomeis called a diploid cell and is said to contain a diploid, or 2n, number of chromosomes.
A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.

the two halves of a doubled chromosome structure are called?
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.

A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
This particular karyotype has 45 chromosomes (instead of the usual 46). "XO" tells us that the karyotype is missing a sex chromosome: the individual has an X, but no homologous sex chromosome (X or Y) to complete the diploid pair.
If a person is missing a chromosome, it is known as monosomy. Monosomy occurs when there is only one copy of a particular chromosome instead of the usual two copies. For example, a person missing one copy of chromosome 21 would have a condition called monosomy 21 or trisomy 21, which is also known as Down syndrome.
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
Unlike the haploid cell which consists of one chromosome, the somatic (diploid) cell contains two chromosomes (one from the mother and one from the father)

A diploid cell is a cell that contains two copies of each chromosome: one from a maternal source and the other is paternal. This occurs in the process of mitosis or the cell division (also called reproduction) of body cells (any cell except the gametes). Diploid cells and the process of mitosis are responsible for growth, cell replacement, and cell/tissue repair.
An abnormal number of chromosomes is called aneuploidy. If a chromosome has 3 of its kind, it is trisomic. The exact condition depends on which gene has the extra chromosome.
