A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). 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)? Both children would inherit the trait.   Both children would not inherit the trait.   Each child has a 50% chance of inheriting the trait.   One child would inherit the trait and one child would not.
