A student is completing a Punnett square for a trait (T/t) that is autosomal and inherited by the dominant allele. The father does not have the trait (tt) but the mother does (Tt). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait?)(1 point)
