QUÉ SIGNIFICA X CHROMOSOME EN INGLÉS
Cromosoma x
El cromosoma X es uno de los dos cromosomas determinantes del sexo en muchas especies animales, incluyendo mamíferos, y se encuentra tanto en machos como en hembras. Es una parte del sistema de determinación de sexo XY y el sistema de determinación de sexo X0. El cromosoma X fue nombrado por sus propiedades únicas por los primeros investigadores, lo que dio lugar a la denominación de su homólogo Y cromosoma, para la siguiente letra en el alfabeto, después de que fue descubierto más tarde.
