Male peacocks display to females but they don’t hold territories and they don’t have contact with females outside of displays and mating. You investigate the role of sexual selection in determining tail length in male peacocks by modifying the length of their tail feathers. You have three treatments: short, medium (= population average), and long. Short and longs are extremes that fall outside of the population’s normal phenotypic range. You measure fitness by counting the number of females that mate with each of the males from each of two populations, Pop 1 and Pop 2. Your results are as follows: Average number of females attracted per male Tail length: Short (75 cm) Medium (100 cm) Long (125 cm) Pop 1 3 15 32 Pop 2 9 19 19 Which population’s results best support predictions common to both the runaway and good genes/handicapped male models of sexual selection? O Pop 1 O Neither Pop 1 nor Pop 2 O Pop 2 The runaway and good genes/handicapped male models of sexual selection share no predictions in common. O Both Pop 1 and Pop 2
