Story summary

University of Iowa biologists report that Potamopyrgus antipodarum, a New Zealand snail, has undergone whole-genome duplication.
The snail reproduces sexually and asexually, and its genome appears as a transitional mosaic with varying gene copies.
Senior author Maurine Neiman of the University of Iowa notes the study, published in Genome Biology and Evolution, that whole-genome duplication may drive innovations and produce complex traits.
