Question

Quizplus · Accepted Answer

If the disorder is present in every generation of the family's pedigree, it is likely that it is a dominant trait. This means that a person only needs one copy of the mutated gene to express the disorder. If it were a recessive trait, it would not be present in every generation because individuals would need to inherit two copies of the mutated gene (one from each parent) to express the disorder. X-linked recessive traits would only affect males in the family, as females would need to inherit two copies of the mutated gene (one on each X chromosome) to express the disorder. Therefore, the best choice is B) dominant.
