Figure 3

rDNA 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.
