The babies have all been separated from their parents because of a
earthquake that affected the hospital. You have been put in charge
of figuring out whose baby is whose! Use your knowledge of
genetic traits to return the babies to the correct parents.

In order to match these babies with their proper parents, you must first
determine the babies' possible genotypes for each trait. Use the following
symbols to represent the dominant and recessive alleles.
W = widow's peak
E = free earlobes
