#Question id: 12288

One way to understand how early environment influences differing behaviours in similar species is through the ? cross- fostering? Experimental technique. Suppose that the curly- whiskered mud rat differs from the bald mud rat in several ways, including being much more aggressive. How would you set up a cross- fostering experiment to determine if environment plays a role in the curly- whiskered mud rat's aggression?

#Unit 10. Ecological Principles

You would cross curly- whiskered mud rats and bald mud rats and hand- rear the offspring.
You would place new-born curly- whiskered mud rats with bald mud rat parents, place new-born bald mud rats with curly- whiskered mud rat parents, and let some mud rats of both species be raised by their own species. Then compare the outcomes.
You would remove the offspring of curly- whiskered mud rats and bald mud rats from their parents and raise them in the same environment.
You would see if curly- whiskered mud rats bred true for aggression.
