  • F1-a  SSLP markers, shown with their map position on A. thaliana chromosomes, were obtained from the supplemental material compiled by Lukowitz et al. (2000) found athttp://carnegiedpb.stanford.edu/methods/ppsuppl.html. Markers that were used in our analysis are shown in bold characters (see “Materials and Methods”).

  • F1-b  The Arabidopsis Ler-derived markers inherited yb each plant are not shown.

  • F1-c  Sizes differ slightly from published sizes.

  • F1-d  Markers for which genotype was inferred as described in “Materials and Methods.”

  • F1-e  The nga6 marker was previously reported not to amplify A. lyrata DNA (van Treuren et al., 1997).

  • F1-f  No amplification.
