For a eukaryotic cell to have only one chromosome it must be a sex cell or a genome in an organism that normally only has 2 chromosomes per cell. I'm not sure if this is exactly what you mean...
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
Haploid
Gametes (sperm and eggs) contain only one sex chromosome.
One copy will be made totalling 2 of the same chromosome, one for each cell.
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
If you mean haploid, as in half of each chromosome, or containing only one chromatid from each full chromosome, thenthe cell is called haploid.

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)
haploid
The process by which a daughter cell accidentally get two copies of a chromosome is called "nondisjuction".

a cell that has one copy of each chromosome is a haploid cell. Cells with 2 copies are known as diploid cells
A sperm cell or an egg cell.
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
