what does being born with an extra y chromosome mean
XYY syndrome XYY syndrome is a genetic condition in which a male has an extra Y chromosome.[1] Symptoms are usually few.[3] They may include being taller than average, acne, and an increased risk of learning problems.[1][3] The person is generally otherwise normal, including normal fertility.[1]
Intersex Intersex people are born with any of several variations in sex characteristics including chromosomes, gonads, sex hormones, or genitals that, according to the UN Office of the High Commissioner for Human Rights, "do not fit the typical definitions for male or female bodies".[1][2] Such variations may involve genital ambiguity, and combinations of chromosomal genotype and sexual phenotype other than XY-male and XX-female.[3][4]
