A normal appearing couple is found to be heterozygous recessive for albinism. Both have the genotype Aa. The gene responsible for albinism is recessive to the normal pigment-producing gene. What are the chances of their children being albino?



Answer :

Where 2 carriers of recessive gene have a child, that child has a 1 in 4 chance of receiving 2 albinism genes and having albinism.
