There is no curent reasurch for XYY syndrome sorry...
Jacob's Syndrome, or XYY Syndrome was first discovered by cytogeneticists Joe Hin Tjio and Albert Levan.
If two are X then its female and vice versa with y. and the disorder is called turner syndrome for females and triple x if all are X and the males is klinefelter syndrome or xyy disorder
In the US, there are currently almost 500,000 people with Down Syndrome.
You would have 47 chromosomes because you would have the normal 46 but one extra y with the sex determing pair of chromosomes which would make you have super male syndrome.
Charge syndrome is genetic. Mutations in a new member of the chromodomain gene family cause CHARGE syndrome. This syndrome is a common cause of congenital anomalies affecting several tissues in nonrandom fashion. Some research has been shown that detected mutations are in the gene CHD7 in 10 of 17 individuals with CHARGE syndrome that didn't have microdeletions, accounting for the disease in most affected individuals.

Yes, Klinefelter's syndrome is due to the XXY genotype.
Yes, it is possible to have XXX, XXY, or XYY sex chromosomes.
Research does not support it.
XYY syndrome is an aneuploidy of the sex chromosomes in which a human male receives an extra Y chromosome. A popular misconception in the 1960s and 1970s that XYY males were more prone to criminal behavior led to several novels and TV series which exploited the idea with little regard to the science.
I don't think there is any. Aurther Shawcross maybe, but not Gacy at least that I know of.
