Figure 3From: Similar patterns of rDNA evolution in synthetic and recently formed natural populations of Tragopogon(Asteraceae) allotetraploidsrDNA repeat inheritance in T. miscellus determined by Southern blot hybridization. (A) Synthetic allotetraploid lines of T. miscellus. (B) Diploid T. pratensis x T. dubius hybrids. (C) Natural populations of T. miscellus. (D) Profiles of parental diploids. Representative individuals are shown in the panels; the rest of the analysis expressed as a ratio of parental bands is shown in Figure 5B. The digests and conditions of the blot and labels are the same as in Figure 2. DU - T. dubius units; PR - T. pratensis units.Back to article page
