directional selection
4
Female birds prefer to mate with brightly colored male birds, which is the most likely outcome?
males will be selected to be brightly colored
females will be selected to choose drab mates
the species will go extinct
females will not mate
5
Which of the following statements about Darwin's voyage of the HMS Beagle is incorrect?
