Hairlessness in american rat terriers is recessive to the presence of hair and is controlled by a single gene. suppose that you have a rat terrier with hair. (a) how can you determine if this dog is homozygous or heterozygous for the hairy trait? give the genotypic and phenotypic results you would expect from any crosses you propose. (b) there is a second gene that controls the phenotype of the hair, with curly hair being dominant to straight hair. you breed two terriers with curly hair (in your evil puppy mill! ) and you end up with 27 pups that have curly hair; 9 pups with straight hair and 12 pups that are hairless! explain this pattern of inheritance using genotype and phenotype!
