Q1
A population of rabbits shows trait variation in coat color: white or brown. The habitat has patchy snow in winter for several years. A researcher records the trait frequencies:
Year 0: white 50%, brown 50%
Year 4: white 30%, brown 70%
Predator observations show hawks catch white rabbits more often than brown rabbits in patchy snow conditions. Traits can affect population outcomes. Which prediction about population traits is supported if patchy snow continues for the next 4 years?
