Phenotypic trait variation in the North American Tragopogon allopolyploid complex.

In Tragopogon, allopolyploidy results in some typical phenotypic changes, including gigas effects and increased photosynthetic capacity. Being polyploid did not produce a significant reproductive advantage. Comparisons between natural and synthetic T. mirus and T. miscellus are consistent with very limited, idiosyncratic phenotypic evolution following allopolyploidization.
