Which syndrome is characterized by the XO chromosome abnormality?
Turner Syndrome! Because women with the disorder only have one X chromosome
What are two diseases linked to the X chromosome?
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.

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.
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
