In humans, cleft chin is dominant to non-cleft chin. Complete a Punnett square crossing an individual whose genotype is heterozygous for the cleft chin trait with another individual who does not have a cleft chin.
1 What is each individual’s genotype?
2.What possible alleles (letters) can be found in each individual’s gametes (the sperm and egg)?
3. These will go on the top and sides of your Punnett square. Set up and complete the Punnett square. You may do this on a separate sheet of paper and insert a photo of your square.
4. After completing the Punnett square, what fraction of offspring will have cleft chin versus no cleft chin?
