The fact that two people without the trait can have offspring with the trait at a frequency of approximately one in four suggests that the trait is recessive. The equal frequency in males and females suggests that it is autosomal rather than X-linked or Y-linked. The trait is not caused by polyploidy as that refers to having extra sets of chromosomes. The fact that the trait appears in the offspring suggests that it is heritable and not a new mutation, ruling out dominant inheritance. Therefore, the best choice is B- recessive, autosomal inheritance.
