You discover a mutation in mice that causes them to suddenly lose their myelin sheaths. How would this mutation change the speed of action potential propagation and why?

Solution

Explanation :-The speed of action potential propagation would lower down due to mutation that cause mice to lose myelin sheath, since myelin sheath on schwann cells is seperated by a gap called node of ranveir where electrical signal jumps by saltatory conduction which speeds up action potential. So mice losing their myelin sheath due to mutation would lower the action potential speed.
