an adnormal number of chromosomes ofter results in
An abnormal condition that a person inherits through the chromosomes or genes is a genetic disorder.
The general term is aneuploidy. Some examples: Down Syndrome is a commonly known condition in which the person has an extra copy, making three, of the 21st chromosome. Others are Edwards Syndrome (an extra 18th) and Patau Syndrome (and extra 13th).
If it had more chromosomes it will cause to down's syndrome
The implications of too many or too few chromosomes from the normal chromosomes are birth defects. With too many chromosomes a child could have Down Syndrome. With too few chromosomes a child could have Turner Syndrome.
Science allows us to actually look at our chromosomes. If we see a third copy of chromosome number 21, we know that a person has down syndrome.
A person inherits Prader-Willi syndrome from the paternal chromosomes. This basically means that you had seven genes that were unexpressed.
In Down syndrome, a person's cells have an extra copy of chromosome 21. In other words, instead of a pair of chromosomes, a person with Down syndrome has three of that chromosome. Down syndrome most often occurs when chromosomes fail to separate properly during meiosis. People with Down syndrome have a degree of mental retardation. Heart defects are also common, but can be treated.

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.
An individual with Down Syndrome has the presence of all or part of an extra 21st chromosome.
