The Punnett square on p. 70 of your lab manual shows the genotypes of two parents for trait R. Use this Punnett square to answer the questions in this exercise. Trait R is the Mendelian trait in humans for tongue rolling. The allele for the ability to roll the tongue (R) is dominant over the allele for the inability to roll the tongue (r). Mom R r R RR Rr Dad r Rr rr1. What is the mother's genotype? 2. What is the mother's phenotype? 3. What is the father's genotype?4. What is father's phenotype? 5. What is the probability of their daughter Maria having each of the possible genotypes and phenotypes? 6. Are you 100% sure of the parents' phenotypes? Are you 100% sure of Maria's phenotype? If not which are problematic? Why? 7. Are you 100% sure of the parents' genotypes? Are you 100% sure of Maria's genotype?
