The chromosomes which are affected in Turner's Syndrome is the sex chromosomes. A normal female individual has 2 X sex chromosomes. In Turner's Syndrome, a woman only has one X chromosome and is missing the other. Thus, a woman with Turner's Syndrome has the sex chromosomes X0.
Yes, Non-disjunction occurs when sex chromosomes fail to separate. This occurrence leads to variable numbers of chromosomes and the manifestation of developmental diseases such as Down syndrome, Turner syndrome, etc.
chromosome 4
Most of the Klinefelter Syndrome affected persons can lead a life which could be considered as normal. However, they might have certain problems related to sexual organs, (among others), and some, - but not all -, could be infertile. The reason for this is their extra chromosome. Females have XX chromosomes, Males have XY chromosomes, and Klinefelter syndrome affected males have XXY chromosomes. They often are prescribed testosterone therapy.

about 1/100,000 people have it.
Hurler Syndrome (named after Gertrude Hurler) is a condition where the lysosomes in the cell become clogged with a mucous-like substance, and are unable to break down cellular waste. This is especially hard on the internal organs (most notably, the kidneys) because they must work harder to filter the blood. Many people are killed by Hurler Syndrome because of organ failure.
Either chromosome 13 or 7. Mostly 13
Forty-seven. In Down syndrome, there is an extra 21st chromosome. It is also known as Trisomy 21.
