WebHow did the icefish antifreeze gene arise? A. The antifreeze gene was caused by a single mutation. B. (Correct) An existing gene was duplicated. It then acquired mutations, which caused it to have a different function. C. Cold Antarctic waters caused the mutation that created the antifreeze gene. D. WebAs the antifreeze proteins circulate through the blood, they bind to ice crystals and prevent them from growing. The fish's blood thus does not freeze and continues to flow normally.
