In hamsters, an autosomal gene (F) controls solid coat pattern that is dominant over spots.  Another gene (E) is sex-linked, and controls the appearance of the tail.  Cotton-tail is recessive to a normal, straight tail. a)    A heterozygous, solid-pattern female, homozygous for normal tail is mated to a spotted, cotton-tail male.  What are the genotypes of the parents?  Use a Punnett square to diagram the cross and show the F1 genotypes.  b)    If a spotted, normal-tailed F1 female is mated to a F1 solid-pattern, normal-tailed male, what are the chances of obtaining a solid-pattern, cotton-tail male hamster?
