此外，左旋和右旋蜗牛可能无法交配，因为它们的扭曲方向不相容。

In addition, perhaps left and right-handed snails cannot mate with each other, having incompatible twist directions.

然而，一些卵壳中会出现反向螺旋的蜗牛，多数情况下是在左旋卵壳中，右旋的出生率惊人地高。

However, some broods possess a few snails of the opposing hand, and in predominantly sinistral broods, the incidence of dextrality is surprisingly high.

如果发现了氨基酸，并且它们普遍表现出同一种偏向性——要么像地球上的氨基酸一样是左旋的，要么是右旋的，那将会格外有趣。

If amino acids are found, it would be especially interesting if they show a prevalence of one type of handedness, either left, like amino acids on Earth, or right.
