Haldane's rule

固有名詞

An observation about the early stage of speciation, stating that if in a species hybrid only one sex is inviable or sterile, that sex is more likely to be the heterogametic sex.

日本語の意味

種分化の初期段階において、交雑種において片方の性だけが生存困難または不妊となる場合、その性は通常、性染色体が異なる（ヘテログマティック、例えばXYやZWの組み合わせ）であるという観察結果を示す法則

Haldane's rule helps explain why hybrid male sterility is common in crosses between closely related species.

雑種で片方の性だけが致死的または不妊である場合、その性が異質染色体性である可能性が高いという観察は、近縁種間の交配で雑種雄の不妊がしばしば見られる理由を説明するのに役立つ。

意味（1）

An observation about the early stage of speciation, stating that if in a species hybrid only one sex is inviable or sterile, that sex is more likely to be the heterogametic sex.

One study hints at the possibility that Haldane's rule may have been the cause of the lack of Neanderthal DNA on the Y-chromosome of hybrids, but currently we do not definitively know.
