Question

A geneticist studying fruit flies hypothesizes that short wings are a recessive trait coded for by a single gene. which observation is most likely to have led her to form this hypothesis? flies with long wings are less likely to survive. flies with short wings prefer to mate with flies with long wings. flies have wing lengths ranging from very long to very short. flies with long wings can produce offspring with short wings.

Answer 1

The observation that is most likely to have led her to form this hypothesis is the fact that flies with long wings can produce offspring with short wings. Recessive traits are the traits that are carried in a person genes without appearing in that particular individual. For example, a dark haired person may have one gene for dark hair, which is a dominant trait, and one gene for light hair, which is recessive.
