Pink-eye and albino are two recessive traits found in the deer mouse Peromyscus maniculatus. In pink-eyed mice, the eye is devoid of color and appears pink because of the blood vessels within it. Albino mice are completely lacking color, both in their fur and in their eyes. F. H. Clark crossed pink-eyed mice with albino mice; the resulting F1 had normal coloration in their fur and eyes. He then crossed these F1 mice with mice that were pink eyed and albino and obtained the following progeny. It is hard to distinguish between mice that are albino and mice that are both pink eyed and albino, so he combined these two phenotypes. Match the expected numbers of progeny with each phenotype if the genes for pink-eye and albinism assort independently. Phenotype Observed Expected
wild type, wild type 12 38
wild type, pink eyes 62 38
albino, wild type or pink eyes 78 76
Total 152 152

Required:
Use a chi-square test to determine if the observed numbers of progeny fit the number expected with independent assortment.
