Is klinefelter's syndrome dominent or recessive?

Is klinefelter's syndrome dominent or recessive?

Error in formation: Humans have 23 pairs of chromosomes. During the formation of the egg, each pair splits and one of each travels to the egg. At conception, the sperm brings 22 + an X or Y & the new embryo now has 23 pairs (two of each). In Kleinfelter, the egg retains 2 X chromosomes instead of 1 & the sperm brings a Y.The fetus then has 23 pairs + the extra X. This is an error in formation, not an inherited trait ...Read more

Trisomy 13 is rare, but a very serious condition. Most babies with it die before birth or shortly after birth. ...Read more
