The Δ508 mutation causes the deletion of three bases from a polypeptide chain. Which statement about this mutation is accurate?
A. The polypeptide chain is unaffected by the mutation because the body can repair the mutation.
B. Because the pattern is in groups of three, the effect of the deletion on the polypeptide chain is minimal.
C. The deletion of the bases has no effect on the rest of the polypeptide chain.
D. In the polypeptide chain, the mutation could change every amino acid that follows the point of the mutation.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
