Fluffy has not been neutered. Who would want the job? He is interested in starting a litter with a French Poodle named Yvette.
Fluffy is homozygous for his dominant pointy teeth (P) while Yvette is heterozygous. Fluffy
is heterozygous for his smooth coat (S) while Yvette is curly haired. Create a Punnett square and summarize the results.
Parental Genotypes:

Results Summary:
- 25% chance of offspring with pointy teeth and smooth coat
- 25% chance of offspring with pointy teeth and curly coat
- 25% chance of offspring with flat teeth and smooth coat
- 25% chance of offspring with flat teeth and curly coat
Given the possible combinations of traits, there is a 50% chance that at least some of the offspring would have Fluffy's pointy teeth and a 50% chance that some of the offspring will have a smooth coat.
