A Genetic Polymorphism Underlying Alternative Reproductive Tactics in Eurycea Salamanders.

Molecular ecology - 1 Feb 2025

Kalki Yatin, Pierson Todd W

Abstract excerpt

Alternative reproductive tactics are discrete, intrasexual differences in reproductive behaviour within a population. In some cases, these complex phenotypes are determined by autosomal supergenes or sex chromosomes-both of which exhibit reduced recombination and thus enable the linked inheritance of co-adapted alleles from multiple loci. Most alternative reproductive tactics in amphibians are plastic (and...
