Abstract excerpt
The evolution of interspecies differences in morphology requires sufficient within-species variation in developmental regulatory systems on which evolutionary forces can act. Molecular analyses of naturally occurring alleles of the Arabidopsis thaliana CAULIFLOWER locus reveal considerable intraspecific diversity at this floral homeotic gene, and the McDonald-Kreitman test suggests that this gene is evolving in a...
