In many large mammal populations, highways can be barriers to movement - individuals rarely cross them. One solution to this problem has been to install overhead bridges for wildlife to safely cross. The goal is to increase gene flow between the populations on either side of the highway. Which of the following would you expect to see if the bridge is successful in its goal? O Higher levels of drift would occur after the bridge is installed The two populations would have different mutation rates Both populations would decrease in size O The two populations would become more genetically similar We would see fewer heterozygotes in both populations
