Selection Maintains the Phenotypic Divergence of Cave and Surface Fish.

The American naturalist - 1 Jul 2023

Borowsky Richard

Abstract excerpt

AbstractGenetic divergence in the presence of gene flow has been well documented, but there is little information on the specific factors maintaining divergence. The present study investigates this in the Mexican tetra (Astyanax mexicanus), an excellent model for studying this question because surface and cave populations differ markedly in phenotype and genotype but are interfertile. Previous population studies...
