When two species are crossed, one has sometimes a prepotent power of impressing its likeness on the hybrid.

物杂交时， 有时有一强大的力量， 可以在杂交上留下自己的相似性。

So I believe it to be with varieties of plants; and with animals, one variety certainly often has this prepotent power over another variety.

所以我相信它与各植物有关; 对于动物来说， 一肯定往往比另一具有这强大的力量。

When distinct SPECIES are crossed the case is reversed, for a plant's own pollen is always prepotent over foreign pollen; but to this subject we shall return in a future chapter.

不同的物杂交时， 情况就相反了， 因为植物自己的花粉总是比外来花粉更有优势； 但我们将在以后的章节中回到这主题。
