Step-by-step explanation:

The 'gene' which CAUSES (inherited, red and green types of) colour blindness is FOUND only on the X chromosome. So, for a male to be colour blind the colour blindness 'gene' only has to APPEAR on his X chromosome. For a female to be colour blind it must be PRESENT on both of her X chromosomes.
