A wasp is a flying insect. In wasps, wing length is coded for by a single gene. Two scientists studying wasps hypothesize that short wings are recessive to long wings. Which of the following observations best supports this hypothesis?

The wings of the wasp have high in length due to the presence of dominant gene.

Explanation:

There are two genes present in wasp which indicates the length of the wing. The recessive gene represents short wing while dominant gene represent high length. So the offspring which is produced from the mating of male and female wasp produces offspring having high length of wings. It is because in the offspring only dominant gene expressed while the recessive gene remain hidden.
