Final Jeopardy
A genetic counselor has gathered the following information.
*Bob and Helen have 3 children.
*Bob and Helen have 1 son who has albinism, an inherited
condition in which the skin does not have brown pigments.
*Bob and Helen have another son and 1 daughter who do
NOT have albinism.
*Neither Bob nor Helen has albinism.
*Albinism is neither sex-linked(only found on the sex
chromosomes X orY), nor co-dominant.
Is albinism controlled by a dominant allele or by a recessive
allele?
