Assume that you find a population of finches in which the members have a bimodal distribution in bill size. Some individuals have a significantly larger bill than others, regardless of sex. Under which condition could disruptive selection maintain this bimodal distribution of bill size? Question 7 options: The population has two major food sources that differ markedly in size. Bills of the intermediate size are difficult to form. In the original population, all of the birds had large bills, but there is continual immigration of birds with small bills into the population. Males use their bills in two different forms of sexual display. Directional selection cannot act on bill size
