Quizplus · Accepted Answer

Given that W = widow's peak and w = continuous hair line and T = roll tongue while t = cannot roll tongue then if the child's phenotype is different for both dominant traits from that of the parent then the parent must be heterozygous for both traits. This would mean that he possess the recessive alleles to pass on to his offspring. His genotype would be WwTt.Bloom's
