Natural Selection In Monkey Flowers

y flowers Some monkey flowers (Mimulus guttatus) living near the sites of copper mines can grow in soil containing high concentrations of copper, which is toxic to most plants. Copper tolerance is a heritable trait. The map below shows the area near an old copper mine, which contaminated the nearby soil with copper. A stream flows past the mine toward the lake at the bottom right of the map. Use the map to determine which of the statements below are true. Select the three statements that are true.

Select the three statements that are true. Nearly 100% of monkey flowers growing in copper-contaminated soil are copper tolerant. If you were to test monkey flowers growing on the shore of the lake, you would expect nearly 100% of them to be copper tolerant. The population that existed before mining must have included both copper-tolerant and copper-intolerant plants. Correct Copper tolerance in monkey flowers is an example of a direct observation of evolution. Natural selection favors the survival and reproduction of copper-tolerant plants in copper-contaminated soils. Therefore, the allele for copper tolerance must have been present in some plants when the soil became contaminated. Because copper tolerance provides no benefit to plants in uncontaminated soils, the trait is not as common in plant populations growing outside the contaminated area.
