EXERCISE 3 INTERPRETING PUNNETT SQUARES
Work in a small group or alone to complete this exercise. The Punnett
square below shows the genotypes of two parents for trait R. 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).
