haploid
The condition in which an individual has three copies of a chromosome is called trisomy. It can result in genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21.
A cell that has two copies of each chromosome is called a diploid cell. This means that each chromosome in the cell has a matching homologous chromosome. Humans have diploid cells in their body, with a total of 46 chromosomes arranged in 23 pairs.
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid."

Tetraploid refers to a cell, organism, or species that contains four sets of chromosomes. This is double the normal diploid number of chromosomes found in most organisms. Tetraploidy can arise through various mechanisms such as cell division errors or hybridization events.
Trisomy 18 is caused by a type of mutation called nondisjunction, where an error in cell division results in an extra copy of chromosome 18. This leads to the presence of three copies of chromosome 18 in each cell instead of the normal two copies.
A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
The 22nd chromosome is called the autosomal chromosome, as it is one of the non-sex chromosomes found in humans. Each cell typically contains two copies of chromosome 22, one inherited from each parent. It contains around 500 to 800 genes involved in various biological functions.
Sister chromatids
Triploid.
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.
The process by which a daughter cell accidentally get two copies of a chromosome is called "nondisjuction".
In one kind of abnormal chromosome inheritance called Down syndrome, a child has three copies of Chromosome 21!
The condition in which an individual has three copies of a chromosome is called trisomy. It can result in genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21.

There will be two copies of each chromosome in all somatic cells called homologous chromosome..In case of reproductive cells there will be only one set during gamete formation...
