Niños-¿Es niño o niña?

Para hacer un bebé, los espermatozoides del padre se reúnen y juntan con el óvulo de la madre dentro de su cuerpo. Dentro de los espermatozoides del hombre se encuentra una serie de instrucciones que le dicen al bebé si debe ser niño o niña.

Las instrucciones en el espermatozoide del hombre pueden llevar la letra "X" o la letra "Y". Si la letra es "X", esto significa que el bebé será una niña. Si la letra es "Y", el bebé será un niño.
