The study examines the genetic complexities behind the invasion of bighead and silver carp in the Mississippi River Basin, focusing on hybridization and genetic adaptation.
It involved sequencing the genomes of these carps and their hybrids, revealing high genetic diversity and genomic similarities between the species, along with traits linked to environmental adaptation.
The findings suggest that the carp's unique genetic features facilitated their initial invasion, while hybridization helped them expand their range, presenting a new perspective on the genetic paradox of biological invasions.
