We returned to the North American members of the genus Dryopteris for the most recent publication out of the lab. Sylvia Kinosian, from Paul Wolf’s lab at Utah State University, led this study that tested the use of double digest RAD sequencing for studying polyploid complexes and determining parentage of allopolyploid species. Our results were mixed, but we think that with larger sample sizes, RAD could be a useful technique for untangling ancestry in reticulate fern complexes.
