- Haldane's Rule
- Haldane's rule is the empirical generalisation, stated by J. B. S. Haldane in 1922, that when one sex of the F1 hybrid offspring produced by crossing two species is absent, sterile, or inviable, it is almost always the heterogametic sex — the sex that carries two different sex chromosomes, whether XY in mammals and Drosophila or ZW in birds and Lepidoptera

Verification¶
Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
