it affects mostly men because men are supposed to have one x and one y chromosome, but they get XXY.
About 1/1000 to 1/500 males have Klinefelter's syndrome.
Because people with Klinefelter syndrome have a Y chromosome, they are all male.
People with Klinefelter's syndrome are not hermaphrodites, and people who are hermaphrodites do not have Klinefelter's syndrome.
The only genotype to cause Klinefelter's syndrome is XXY.
Mr. Klinefelter
what is kinefelter syndrome?
there are five base pairs in klinefelter syndrome
Klinefelter's syndrome was first identified in 1942 by Harry Klinefelter and his colleagues. They described a group of men with underdeveloped testes and other characteristic features that became known as Klinefelter's syndrome.
Klinefelter's syndrome is not considered to be a variation of normal, so by definition it is abnormal.
No race is more likely to spontaneously have issues with meiosis, and as Klinefelter's is not hereditary (anyone with it is infertile and cannot pass on genes) no race will become more likely to have Klinefelter's syndrome. The population of older women who have children is more likely to have Klinefelter's babies. Older women are less likely to miscarry a baby with a chromosomal defect, so more Klinefelter's babies are born to them.
The genotype for a person suffering with Klinefelter's syndrome is XXY.
No, Klinefelter syndrome and Turner syndrome are the result of nondisjunction of sex chromosomes. Klinefelter syndrome is caused by an extra X chromosome (XXY), while Turner syndrome is due to a missing X chromosome (XO).
