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

当两个物杂交时， 有时有一强大的力量， 可在杂交上留下自己的。

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

所我信它与各植物有关; 对于动物来说， 一个品肯定往往比另一个品具有这强大的力量。

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.

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