t is the gene for tongue rolling.
Provide the genotype & phenotype?
Person A is homozygous recessive for gene t.
Person B is heterozygous for gene t.
Ratio of chances (this can be a fraction, a punnet square, whatever you best remember)
Person A = tt/no tongue rolling
Person B = Tt/yes tongue rolling
Ratio of chances: 2 can roll tongue (tT) and two can't (tt)
