Textbook Question
Chapter 24.1, Problem 2CC
WHAT IF? Ø Suppose two bird species live in a forest and are not known to interbreed. One species feeds and mates in the treetops and the other on the ground. But in captivity, the birds can interbreed and produce viable, fertile offspring. What type of reproductive barrier most likely keeps these species separate in nature? Explain.

WHAT IF? Imagine two populations of a fish species,one in the Mediterranean Sea and one in the CaribbeanSea. Now imagine two scenarios: (1) The populationsbreed separately, and (2) adults of both populationsmigrate yearly to the North Atlantic to interbreed. Whichscenario would result in a greater loss of genetic diversityif the Mediterranean population were harvestedto extinction? Explain your answer.
WHAT IF? Consider two species that diverged whilegeographically separated but resumed contact beforereproductive isolation was complete. Predict the outcome over time if the two species mated indiscriminately and (a) hybrid offspring survived and reproducedmore poorly than offspring from intraspecific matingsor (b) hybrid offspring survived and reproduced as wellas offspring from intraspecific matings.
WHAT IF? In the deserts of New Mexico, the soils aremostly sandy, with occasional regions of black rockderived from lava flows that occurred about 1,000 yearsago. Mice are found in both sandy and rocky areas, andowls are known predators. What might you expect aboutcoat color in these two mouse populations? Explain. Howwould you use this ecosystem to further test the camouflage hypothesis?
