| Description: In the snails shown in this experiment, the direction of body coiling is controlled by a single pair of genes. D (dextral, or right-handed) is dominant to d (sinistral, or left-handed). The genotype of the mother determines the phenotype of the offspring. A DD or Dd mother will produce dextral offspring and a dd mother will produce sinistral offspring, regardless of the genotypes of the father and of the offspring themselves.
