2.6 Evolutionary consequences of transition to homostyly
Using microsatellites, we tested whether the transition to homostyly is associated with a shift of mating system by estimating outcrossing rates from the progeny arrays and selfing rates from the 22 natural populations with variable frequencies of HO-morphs. Moreover, we tested whether the frequency of homostyles is positively correlated with levels of inbreeding within populations and of genetic differentiation among populations.
