Why is it that a mongoloid person have 65 chromosomes?
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.
What is the term for three chromosomes instead of two?
The term for having three chromosomes instead of the usual two is "trisomy." This condition occurs when there is an extra copy of a chromosome, leading to a total of three copies instead of the normal pair. Trisomy can result in various genetic disorders, the most well-known being Down syndrome, which is caused by an extra copy of chromosome 21.
How many chromosomes does a person with Down Syndrome have?
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.
What if you have 47 chromosomes?
Having 47 chromosomes is an abnormality known as aneuploidy. It can result from errors during cell division or genetic conditions like Down syndrome or Klinefelter syndrome. Aneuploidy can lead to developmental issues and health complications.

It is certainly possible to have more than 46 as in Trisomy 21 (or down syndrom) where "one cell has two 21st chromosomes instead of one, so the resulting fertilized egg has three 21st chromosomes".
What does down syndrome mean?
it means that you have 47 chromosomes instead of 46.
How does the number of chromosomes in sex cells compared with the number of chromosomes in body cells?
Sex cells have 23 chromosomes compared to the body cells' 46 chromosomes. This is because a child is created from half the genome of its father and half the genome of its mother. In other words, 23 chromosomes in the mother's egg and 23 chromosomes in the father's sperm, when combined generate a child with 46 chromosomes in its body cells. However, sometimes mutations occur where more of fewer chromosomes are passed down, this will either result in no embryotic development or the embryo having some kind of syndrome.
