Use the following to answer questions In the late 1940s Edward Lewis discovered mutations in the Antennapedia gene that lead to legs developing on the head of a fly instead of antenna. These mutations are dominant and lead to ectopic expression of the Antennapedia gene. -Certain mutations in the Antennapedia gene can lead to antenna developing in a mesothoracic segment where legs should have developed. What characteristics would you expect from this class of mutations? (Select all that apply.)
A) They are loss-of-function. B) They are recessive. C) They are gain-of-function. D) They are dominant. E) They result in ectopic Antennapedia expression.
