In Ukraine, there are entire stretches of forest that were doused with radioactive material after the Chernobyl nuclear reactor disaster in 1986. Humans have abandoned the areas most contaminated by radioactivity, but many species of plants and wildlife have flourished. Unfortunately, though, there is still a significant amount of radioactivity saturated in the soil and water, and the radiation it emits has an effect on the DNA of the local populations of organisms.
One of the Hardy-Weinberg assumptions is that the population is large-in its strictest sense, that the population is infinitely large. The preceding scenario obviously violates this assumption in its strictest sense, because no real population is infinitely large. Which of the other four Hardy-Weinberg assumptions does this scenario violate?
A. Mating is random.
B. No net mutations occur.
C. There is no migration.
D. There is no natural selection
