An environment that would tend to reduce genetic variation in a population due to evolution by natural selection is **grasslands that are undergoing severe drought**. Severe drought conditions can create strong selective pressures, favoring certain traits that help individuals survive in that specific environment. This can lead to a reduction in genetic variation, especially if only a few individuals with advantageous traits reproduce successfully. Over time, this can diminish the overall genetic diversity of the population.
