    Heredity (Edinb) 98:143-50. 2007
    ..In spite of the inefficiency of unreduced pollen in unilateral sexual polyploidization, the overall rate of neohexaploid formation (one in 233) was several orders of magnitude greater than estimates of genic mutation rates...

    Department of Integrated Biology, University of Guelph, 488 Gordon St, Guelph, ON N1G 2W1, Canada
    Evolution 62:639-53. 2008
    ..These results affirm the "ecotype" concept of the North American Achillea advocated by classical research and demonstrate the rapid rate of ecological differentiation that sometimes occurs in plants...
