Textbook Question
Chapter 13, Problem 15TYK
A population of snails is preyed on by birds that break the snails open on rocks, eat the soft bodies, and leave the shells. The snails occur in both striped and unstriped forms. In one area, researchers counted both live snails and broken shells. Their data are summarized below:

Say there is a population of plants that live in a wetland, and are adapted to tolerate both flooding and drought. One year, the wetland floods completely, and only the most water-tolerant plants are able to survive. The wetland never drains, and over many years the plants adapt to stay submerged all year. Many generations later, the wetland returns to being wet and dry, and the entire population dies out.
Is this an example of a historical constraint or genetic correlation?
What long-term effects can gene flow have on any two populations that are exchanging genes?

A population of lizards in Northern California is brown and is not poisonous to birds. A population of lizards in Southern California is orange and is poisonous to birds. In central California, where the two species overlap, a new species of non-poisonous, orange lizards arose. Which of the following statements best explains the existence of non-poisonous orange lizards?
A) Non-poisonous brown lizards changed color once they noticed birds did not eat orange lizards.
B) Non-poisonous orange lizards have a selective advantage since birds avoid orange lizards.
C) Non-poisonous lizards turn orange by eating orange flowers and then pass the trait on
D) Non-poisonous orange lizards have a selective disadvantage since they cannot blend in.
E) Non-poisonous brown lizards are more attractive to mates.
