You want to study divergence of populations, and you need to maximize the rate of divergence to see results within the period of your grant funding
You will form a new population by taking some individuals from a source population and isolating them so the two populations cannot interbreed. What combination of characteristics would maximize your chance of seeing divergence in this study? 1. Choose a random sample of individuals to form the new population. 2. Choose individuals from one extreme to form the new population. 3. Choose a species to study that produces many offspring. 4. Choose a species to study that produces a few, large offspring. 5. Place the new population in the same type of environment as the source population. 6. Place the new population in a novel environment compared to that of the source population. A) 1, 3, and 6 B) 1, 4, and 6 C) 2, 3, and 5 D) 2, 3, and 6
