If one child is albino and other visually impaired, could the impaired child be a carrier of albino gene?

Albino inheritance: There are 2 types of albionos: those with involvement with skin, eyes and hair and those with just eye involvement. It is possible that your child in fact has albinism so make sure you ask your eye doctor to check for that. On the other hand he cause of albion is a recessive gene or a random mutation - rare. There is a 1/4 chance he inherited the gene from his parents.
