Assignment Help Answers with Step-by-Step Explanation:
Differential survival and reproduction: While the graphs do not directly show differential survival and reproduction, the study mentions that during the severe drought, the finch population was greatly reduced, and most deaths were due to starvation. This implies that finches with certain beak depths might have been better adapted to access the available seeds, which could lead to differential survival and reproduction during the drought.
10. If the "wet year" hypothesis is true (meaning that finches with larger beaks are better adapted to access food during wet years), you would predict the following changes in the distribution of beak depth measurements after the drought:
The frequency distribution in Figure 3 might remain relatively similar or not shift significantly to the left or right.
This would suggest that beak depth is still subject to some form of selection, even during drought years, and that the heritability of beak depth continues to play a role in the population's adaptation.
