1. A homozygous blue-eyed mouse with short whiskers mates with a homozygous brown-eyed mouse with long whiskers. All of their offspring have brown eyes and short whiskers. Which alleles are dominant? 2. A homozygous five-clawed cat is crossed with a homozygous six- clawed cat and all of the kittens have six claws. Which allele is dominant? 3. In humans, the five-fingered condition is recessive to the six-fingered condition. Yet, most people have five fingers. Explain how this can happen.
