Vallejo-Marin M, Cooley AM, Lee MYQ, Folmer M, McKain MR & Puzey JR (2016) Strongly asymmetric hybridization barriers shape the origin of a new polyploid species and its hybrid ancestor, American Journal of Botany, 103 (7), pp. 1272-1288.
PREMISE OF THE STUDY:Hybridization between diploids and tetraploids can lead to new allopolyploid species, often via a triploid intermediate. Viable triploids are often produced asymmetrically, with greater success observed for “maternal-excess” crosses where the mother has a higher ploidy than the father. Here we investigated the evolutionary origins ofMimulus peregrinus, an allohexaploid recently derived from the triploidM. ×robertsii, to determine whether reproductive asymmetry has shaped the formation of this new species.
