Mitochondrial structure despite nuclear panmixia: sex-specific dispersal dictates population structure in sperm whales.

Heredity - 1 Apr 2026

Abstract excerpt

Marine mammals have high potential for dispersal, yet behavioral or environmental constraints can limit gene flow. This is true for the endangered sperm whale, Physeter macrocephalus, which has a global distribution and long-distance migrations. While previous studies revealed mitochondrial population structure with weak nuclear structure globally, genomic approaches examining this pattern have been limited....
