The paper investigates how water pollution affects hybridization between two swordtail fish species by analyzing genomic and environmental data.

This study identifies two melanic pigmentation patterns in Xiphophorus nezahualcoyotl linked to the sex chromosome-linked oncogene xmrk through long-read sequencing and GWAS.

This study identifies a retrovirus insertion near the alkal2a gene as the genetic basis for a novel iridescent color trait in swordtail fish, showing its role in chromatin changes and predator interaction signals.

The paper uses admixture mapping in swordtail fish hybrids to identify mitonuclear incompatibilities, finding nine genomic regions involved in interactions between nuclear and mitochondrial genomes.

This study shows that despite strong reproductive barriers, gene flow is pervasive between closely related swordtail fish species through hybridization and genetic incompatibilities.

The paper identifies a genetic basis for a sexual mimicry polymorphism in swordtail fish and links it to behavioral interactions that may maintain the polymorphism.

The paper introduces mixnmatch and ancestryinfer, tools for simulating admixture scenarios and inferring local ancestry, highlighting factors affecting inference accuracy.
