Fruit bats can have ear shape [oval and large (O) or pointed and small (P)], and nose size [narrow (N) or wide (W)]. Assume that each trait is caused by a single gene in which one allele is completely dominant to the other.

Look at the table to the right and determine the dominant and recessive alleles for ear shape and nose size.

Once you've figured those out, you can next determine the genotypes of the parents.
