By definition Klinefelter's syndrome is genetically XXY. If there is any Y chromosome present, the baby will develop into a boy.
Even if a baby had XXXXY, it would still turn out as a boy.
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.
They get Klinefelter syndrome. They have male sex organs, but the testes are abnormally small and the man is sterile. Even though the extra X is inactivated, some breast enlargement and other female body characteristics are common.
About 1/1000 to 1/500 males have Klinefelter's syndrome.
Klinefelter's syndrome is not considered to be a variation of normal, so by definition it is abnormal.
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).
The parents have normal genotypes, because Klinefelter's syndrome is not inherited.
