Dark-colored mice from two different populations living hundreds of miles apart were examined. The mice looked nearly identical, but their dark color was caused by two different genes. What does this tell you?

They have a genetic mutation that affects their fur color.

Explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
