45,X/46,XY Mosaicism is a rare intersex trait affecting 1 in 15,000 people where some of your cells have sex chromosomes split, where some of your cells may have XX chromosomes and some may have XY chromosomes. This is one of many different forms of intersex traits showing that sex, rather then a black and white binary system is a spectrum, as many people do not easily fit into the categories of male or female.
