Klinefelter's Syndrome is a mutation.

How is the Klinefelter's Syndrome inherited?

Klinefelters isn't inherited by a parent it happens randomly during Nondisjunction.

Klinefelter's syndrome is sex-linked because its a genetic defect that results in a male having an extra X chromosome during Nondisjunction.

It is located on the XY chromosome.

Klinefelter's Syndrome is neither Recessive or Dominant.

How is Klinefelter's Syndrome treated?

Klinefelter's Syndrome is very rare, it only occurs in 1 in 50,000 or fewer newborn males.

Application of Research Article

The new information I learned from my research is that only males can get this disease. Also, the male can get an extra chromosome which i didn't know. Also that Kinfelter's Syndrome can only occur to males. Klinefelter's Syndrome is incurable. It's very rare for males to get this disease. Also, that Klinefelter's Syndrome isn't inherited.
