Genotypes of Mother, Father, and Child in Tongue Rolling

Tongue rolling (T) is the dominant trait over not being able to roll your tongue (t) (Kim, 2020). A woman who can roll her tongue marries a man who cannot, and their first child can roll. To determine the genotypes of the mother, father and child, we must look at the potential combinations of the traits. The mother’s genotype must be TT, as she can roll her tongue, while the father’s genotype is tt, as he can not roll his tongue (Choi, 2021). The child’s genotype could be either TT, Tt or tt. The most likely combination is Tt, as it is the combination of the mother’s dominant trait and the father’s recessive trait.
In conclusion, the genotypes of the mother, father, and child are TT, tt, and Tt respectively. Both parents contribute a T and a t to their child, allowing the dominant trait of tongue rolling to be expressed in their child. Cont…
