I was going to make a post about this but it looks like you guys have a good chat going. My inquiry was about introgression. If we have introgression, this is valuable information, but the specimen may only be 10% species A, and 90% species B. Imagine there existed species A, a rare native species. An alien species (B) in the same genus was introduced in proximity to the last disjunct population of species A, in 1824 and started crossing with A. This was left undocumented for decades, until a biologist noticed pedunculate fruit on a species that has sessile fruit. He visits a local herbarium and finds specimens of species A, that were misidentified, proving they were there in the 1830s. How would you label the spcimens that remain growing wild? they are on average 90% invasive (species B) but the small amount left is visible in some specimens, and making sure the species A signal is described is important data. Would this be labelled a hybrid? is this enough DNA to be considered a hybrid or would it be labelled as the next higher taxon? Thanks.
