My Flashcards

Definition

Meaning

A proper noun primarily referring to a surname, most famously associated with the evolutionary biologist and geneticist J.B.S. Haldane, and his father, the physiologist J.S. Haldane.

The name can refer to individuals, families, or concepts (like 'Haldane's principle', 'Haldane's rule') in evolutionary biology and physiology. It is also occasionally found in place names or as a first name.

Linguistics

Semantic Notes

Used almost exclusively as a proper noun. In scientific contexts, it is associated with specific principles in genetics and evolutionary theory.

Dialectal Variation

Connotations

In academic circles, strongly connotes evolutionary biology and population genetics.

Frequency

Equally rare in both dialects outside of specific academic fields.
