Question

Quizplus · Accepted Answer

The ability to taste PTC (phenylthiocarbamide) is a genetic trait governed by a dominant allele (T for tasters) and a recessive allele (t for nontasters). Two nontasters have the genotype tt and can only pass on the t allele to their offspring, resulting in offspring who are also nontasters (tt).
