colour blindness is genetic

colour blindness is past on through the genes. Grandfather is colour blind and carry the genes to his daughter. but because girl have two x the good one counter out the effected one. She then has a 50% chance of pass it on to her sons and daughters.
Boy have only one x so if they recieve the gene then became colour blind. Girls have to recieve the gene from both sides of the family to became colour blind.

two questions here ...
on yr first one:
you could have too much exposure to computer light from the monitor (over the years it does damage the eyesight)
you could have glaucoma
you could have a tumor in yr nearby optical nerve
yo could be born color blind
on yr second questions why dont you try carrying something heavy yourself and see what happens?
