There are two types of american rat terrier dogs those without hair and those with hair the presence of hair is a genetically determined trait. some female rat terriers with hair produce only puppies with hair, whereas other females produce rat terrier puppies with put hair. explain how this can occur
Phenotype depends on two alleles: one from mom and one from dad. If a puppy inherited the dominant trait of hair from one or both parents, it will have hair. If it inherited recessive traits from both parents, it will be hairless.
