biology question help please confused?

Turner syndrome is caused by a missing or incomplete X chromosome.

Kleinfelter syndrome is a disorder that affects only males. Males normally have one X and one Y chromosome. But males with this syndrome have an extra X chromosome (XXY) giving them 47 rather than the normal 46 chromosomes.

"Klinefelter syndrome is typically caused by what is called nondisjunction. If a pair of sex chromosomes fails to separate during the formation of an egg (or sperm), this is referred to as nondisjunction. When that egg unites with a normal sperm to form an embryo, that embryo may end up with three copies of the sex chromosomes (XXY) instead of the normal two (XY). The extra chromosome is then copied in every cell of the baby's body."

However, since the male receives the X chromosome from his mother, and the Y from the father, it is NOT due to nondisjunction during spermatogenesis, but spermatogenesis, but nondisjunction during oogenesis.

Nondisjunction would have to occur in the father for their to be two YY chromosomes. Which would be a genetic disorder called Jacob Syndrome. (XYY) If normal oogenesis occurred it would be XYY. If abnormal Oogenesis occurred and normal spermatogenesis occurred it would be XXY or XXX. XXY-Klinefelter, XXX-Poly-X syndrome.

Supermale 47,XYY. Both Y chromosomes come from Dad.
