Population genomics and subgenome evolution of the allotetraploid frog <i>Xenopus laevis</i> in southern Africa

Abstract

AbstractAllotetraploid genomes have two distinct genomic components called subgenomes that are derived from separate diploid ancestral species. Many genomic characteristics such as gene function, expression, recombination, and transposable element mobility may differ significantly between subgenomes. To explore the possibility that subgenome population structure and gene flow may differ as well, we examined genetic variation in an allotetraploid frog—the African clawed frog (Xenopus laevis
