[HL Content] A population of snails exhibits a shell coiling polymorphism, where some individuals have right-coiling (dextral) shells and others have left-coiling (sinistral) shells. The direction of coiling is controlled by a single gene. Due to the mechanics of snail anatomy, dextral individuals can only successfully mate with other dextral individuals, and sinistral with sinistral. A mutation causing a switch in coiling direction in an individual's offspring could potentially lead to:
What potential evolutionary event could be triggered by a single gene mutation affecting shell coiling in snails?
