Data Table 1 – Phenotype and Genotype Trait Dimpled Chin Free Ear Lobe Phenotype & Genotype from Parent A Phenotype & Genotype from Parent B dimpled chin Dd attached ear lobe aa Ability to Taste PTC Strips ability to taste Interlocking Fingers right thumb over left Mid-digital Hair Bent Little Finger Widow’s Peak Pp ff hair on joints HH little finger bends Bb straight hairline ww Hitchhiker’s Thumb bent thumb Blue or Green Eyes green eyes Rolled Tongue TT ee rolled tongue Ll Prepared Punnett Squares 1 Offspring There are 20 squares provided; two for each trait. Use these Punnett squares to show both the genotype and phenotype ratios for each of the traits.

As “Parent B”, how many recessive traits did you express? What were they? 2. As “Parent B”, how many dominant traits did you express? What were they? 3. As “Parent B”, what is the likelihood or chances of you passing a dominant allele onto your “offspring” for the following traits: a. Dimpled chin b. Free ear lobe c. Ability to taste PTC d. Brown eyes 4. What is the likelihood or chances of your “offspring” receiving a recessive allele for the following traits: a. Widow’s peak b. Hitchhiker’s thumb c. Green eyes d. Rolled tongue 5. While the traits studied in Exercise 1 were hypothetical genetic traits, what type of genetic traits do you think are important to study and predict?
