Question

Quizplus · Accepted Answer

The coiling of shells in snail offspring is determined by the mother's genotype. This is because snails have a maternally-inherited gene that controls the direction of shell coiling. Therefore, the mother's genes dictate the offspring's shell coiling direction. The father's phenotype or genotype does not have an impact on the shell coiling of the offspring.
