What probably explains why coastal and inland garter snakes react differently to banana slug prey?

#Unit 10. Ecological Principles
  1. Ancestors of coastal snakes that could eat the abundant banana slugs had increased fitness. No such selection occurred inland, where banana slugs were absent.
  2. Banana slugs are difficult to see, and inland snakes, which have poor vision compared with coastal snakes, are less able to see them.
  3. Garter snakes learn about prey from other garter snakes. Inland garter snakes have fewer types of prey because they are less social.
  4. Inland slugs are distasteful, so inland snakes learn to avoid them. Coastal banana Slugs are not distasteful.

#Unit 8. Inheritance Biology

You set up an experiment in which you breed two populations of true-breeding pea plants. The first true-breeding population has yellow round seeds and the second has green wrinkled seeds. All of the F1 plants yield yellow round seeds. When you self -fertilize the F1 the F2 generation yields a mixture of yellow round, yellow wrinkled, green round and green wrinkled seeds. What does this tell you about the alleles for seed color and shape?
