Question

1. If the ability to taste PTC were controlled by only two alleles: one dominant (T) and one recessive (t), would there be any way to distinguish between the heterozygous (Tt) individuals and the homozygous dominant (TT) individuals without mating or performing DNA analysis? Explain your answer.

Answer 1

Answer:No

Explanation: there would not be a way to distinguish between Tt and TT without mating or DNA analysis because T is dominant in Tt, therefore has the same physical characteristics as TT.
