 * __ Transmission __**

Klinefelters syndrome is in herited by chance, due to occasional abnormalites in either an egg or sperm resulting from an error in meosis. Here are the steps:


 * 1)** An egg develops into a double X chromosome haploid cell (XX)


 * or**

A sperm develops into an X and Y chromosome haploid cell (XY)


 * 2)** The (XX) egg fertilizes with a regular Y sperm.


 * or**

The (XY) sperm fertilizes a regular egg.


 * 3)** A zygote develops with an (XXY) abnormality.


 * 4)** A fetus develops, baby is born, and child develops with XXY Condition/Klinefelters Syndrome​.


 * Aditional Information:**

This is a sex-linked disorder, where a new sex (XXY) develops and not (XX)-female or (XY)-male.

Because the Klinefelter syndrome is caused by abnormalities that occur by chance in meosis, it is not an inherited disorder
