33. Imagine that you sample 100 plants from five populations, then sequence several of their genes. Across the entire sample of all five populations, there are fewer heterozygotes than expected under Hardy-Weinberg equilibrium. Within each population, the genes show linkage disequilibrium. What could explain those results? (5 pts) 34. Describe when selection will be a much stronger force than drift, and vice versa. (5 pts) 35. Explain why genetic drift is such a big concern for endangered species. (5 pts).
