3. Predict the possible appearance of the children of Bob andSue Everyperson, a young couple who now live in
Centralia. We are tracking two genes: hair line and earlobes.These genes are located on non-homologous
chromosomes. The allele for widows peak (W) is dominant to theallele for a smooth hairline (w). The allele for free
ear lobes (F) is dominant to the allele for attached ear lobes(f). Bob’s genotype is WwFf. Sue’s genotype is wwff.
3a. What type of hair line and earlobes does Bob have? What typeof hair line and earlobes does Sue have?
3b. How many different gametes can Bob produce? List thesegametes? How many different gametes can Sue produce? List thesegametes.
3c. Using a Punnett square, show the genotype and phenotype ofall possible combinations between the
gametes from Bob and Sue. What is the likelihood that theirfirst child will have a widow’s peak and attached
ear lobes?
