Down syndrome is when you have a trisomy of chromosome number 21. So that means they have 47 chromosomes.
An older name for Down Syndrome is Mongolism. That was considered a racist term because it made fun of the features of people from Mongolia. Its use was dropped in 1965 after a delegate from Mongolia asked that the name be dropped as a medical term.
All humans, other than those with genetic disorders such as Down Syndrome, have 23 pairs of chromosomes, no matter what their skin color is. Skin color does not have anything to do with how many chromosomes a person has.
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
A human reproductive cell, also known as a gamete, contains 23 chromosomes. This is half the number of chromosomes found in regular body cells, which have 46 chromosomes.
A person with Edwards syndrome (Trisomy 18) has an extra copy of chromosome 18, resulting in a total of 47 chromosomes instead of the typical 46. This additional chromosome can lead to developmental abnormalities and health complications.
If you mean how many; there are 46, or 23 homologous pairs. There are 22 autosomal pairs and the sex chromosomes (X and X/Y). This can vary in some disorders, such as Down Syndrome, Turner Syndrome, Klinefelter's Syndrome, and Triple X Syndrome.
The same as all of the other cells.

47There are 47 chromosomes in someone with Down syndrome; the 21st pair has an extra chromosome. Most people have 46 chromosomes. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes on their 21st pair.

Forty-seven. In Down syndrome, there is an extra 21st chromosome. It is also known as Trisomy 21.
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
Having too many chromosomes, a condition known as aneuploidy, commonly leads to genetic disorders such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13). These conditions can result in a range of physical and developmental challenges, impacting an individual's health and well-being.
