The X chromosome is ane o the twa sex-determinin chromosomes (allosomes) in mony organisms, includin mammals (the ither is the Y chromosome), an is foind in bauth males an females. It is a pairt o the XY sex-determination seestem an X0 sex-determination seestem. The X chromosome wis named for its unique properties bi early researchers, that resultit in the namin o its coonterpairt Y chromosome, for the next letter in the alphabet, efter it wis diskivered later.[5]
