Polyploid or triploid.
Down syndrome is trisomy 21
Organisms can have two copies of each chromosome, one from each parent. This is known as diploid. Other organisms, like plants, can have more than two copies of each chromosome (polyploidy). Having multiple copies of chromosomes can affect gene expression and traits in organisms.
The presence of three copies of a chromosome is known as a trisomy. An example would be Trisomy 21, also known as Down Syndrome.
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
People with Down syndrome, also called mongoloidism have 47 chromosomes. Having 65 chromosomes would be lethal, as normally having 47 chromosomes is lethal. Down syndrome is also known as trisomy 21, because instead of two copies of chromosome 21, a person with Down syndrome has three copies, which accounts for the 47th chromosome.

Yes, chromosomes make copies of themselves through a process called DNA replication. During cell division, each chromosome is duplicated to ensure that each daughter cell receives an identical set of genetic material.
Trisomy-21, also known as Down syndrome, results from an extra copy of chromosome 21. Instead of the usual two copies, individuals with Down syndrome have three copies of chromosome 21. This extra genetic material can lead to various physical and cognitive differences.
diploids cells have set (S)of chromosomes
The condition in which an organism has complete extra sets of chromosomes is called polyploidy. This condition can cause a number of severe birth defects. Most do not live a full lifespan for their species.
