In rabbits car shape pointed vs round is determined by a sin

In rabbits, car shape (pointed vs. round) is determined by a single autosomal gene. Two pointed cared rabbits have a litter consisting of a mixture of pointed eared and round cared offspring. What can be said about the inheritance of this trait? Pointed ears is dominant to round ears Pointed ears is recessive to round ears Round ears is dominant to pointed ears This gene for ear shape is on the X chromosome The pointed ear and round ear genes assort independently

Solution

11. The answer is: a. Pointed ear is dominant to round ears

The parent rabbits are heterozygous and so recessive trait is also seen in the litter.
