The gene for long beaks will increase.
As the trees in the habitat are affected by disease, the insect population may decrease or move to different areas, making it more difficult for the bird species with shorter beaks to access food. This could lead to a higher survival rate for birds with longer beaks, resulting in an increase in the frequency of the gene for long beaks in the bird population.
A species of bird eats insects. The longer its beak, the better it can reach insects in holes in trees A disease affects the trees in the habitats of the insects. How might this change the frequency of the gene for a long beak?
