Anormal 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? . a) 3: 4 children will be albino. b) all children will be albino. c) 1: 4 children will be albino.
