Life cycle variation in A. thaliana. (A) The length of the major life stages in natural populations in Italy (red) and Sweden (blue). Filled areas: seed stage, hatched areas: vegetative stage; dotted areas: reproductive stage. (B) Change in frequency of the Swedish allele at the marker closest to the mean point estimate of the fitness QTL Q9 within one generation in the RIL population planted in Italy (red) and Sweden (blue). The frequency of the Swedish allele is given among seeds planted (Seed), among established seedlings (Seedling), among plants alive at harvest (Adult), and among fruits produced (Offspring, based on RIL median number of fruits produced).
