¨The abnormalities common to cat eye syndrome were first cataloged in 1898
Marfan disease was found in 1896, by a French doctor named Antione B. Marfan
Small dog syndrome is when your dog believes he's the leader
Short Spine Syndrome (Brachyrachia) is a condition characterized by a short spinal column due to compression of the vertebrae
Marfan syndrome is not sex linked. It is autosomal dominant and found equally in all genders and ethnicities.
Jacob's Syndrome, or XYY Syndrome was first discovered by cytogeneticists Joe Hin Tjio and Albert Levan.
There is no curent reasurch for XYY syndrome sorry...
Nondisjunction in Meiosis 2
XYY Syndrome
There are seven possible genetic sexes: XX = female XY = male X = female with Turner syndrome XXX = female with X-trisomy XXY = intersex with Klinefelter syndrome XYY = male with 47,XYY syndrome XXYY = male with 48,XXYY syndrome
excellent prognosis. men with xyy syndrome (jacob's syndrome) live comfortably.
Yes, Klinefelter's syndrome is due to the XXY genotype.
Yes, it is possible to have XXX, XXY, or XYY sex chromosomes.
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.
Superman Syndrome is when a male has XYY for sex chromosomes. This was first discovered when researchers began studying male aggression in inmates. They found this extra sex chromosome and tried to find the link between the two. No correlation was found. Symptom's of Superman Syndrome are unusual height, average to low IQ's, and a slight increase in aggression. One in 2000 men have this, and it is likely that you know someone with this disorder.
I don't think there is any. Aurther Shawcross maybe, but not Gacy at least that I know of.
XYY syndrome can be said to be "dominant" because if a person has it, they have it. there is no having a recessive gene for this. However, technically, it is neither. XYY syndrome is not inherited, and usually occurs at random during formation of sperm cells. This happens as an error in Chromosome separation during Metaphase II. Sometimes it happens as a result of nondisjunction during cell division during a post-zygotic mitosis in embryonic development. This produces 46,XY/47,XYY.
