Mc1r gene in Astroblepus pholeter and Astyanax mexicanus: Convergent regressive evolution of pigmentation across cavefish species.

Developmental biology - 15 Sept 2018

Espinasa Luis, Robinson Jenna, Espinasa Monika

Abstract excerpt

Cave-adapted organisms are often characterized by a reduction in pigmentation, eyesight, and enhanced mechanosensory functions. Previous studies have described the genetic basis for a depigmented phenotype in multiple independent populations of the Blind Mexican Tetra, Astyanax mexicanus; the reduction in melanin content (brown; Mc1r). At least seven wild populations express the brown phenotype. In three...
