trisomy
There several types of trisomy, the most well known is probably Down syndrome, which is trisomy 21.
Fragile X Syndrome
Fragile X Syndrome
If someone has an extra chromosome it means there was a genetic mutation that is abnormal in human development. It may result in problems with the person affecting them on a basic level, or may go fully unnoticed. A common disorder that can be caused by having an extra chromosome is Down's Syndrome.
Chromosomal, because the person with Klinefelter's would have 47 chromosomes. A genetic disorder would be any disorder having to do with genes, but would not necessarily mean having an extra chromosome.
Chromosomal additions occur when an extra piece of a chromosome is added. This can lead to genetic abnormalities and developmental disorders in individuals. The extra genetic material can disrupt the normal function of genes on the affected chromosome.
Fragile X Syndrome
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).

Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.
Also referred to as trisomy 21. Down Syndrome.
Down Syndrome is when there is an extra chromosome in someones DNA. More exactly it is when the 21st chromosome has an extra one.
