Comparison of the Genetic and Physical Maps.

(A) Marker bin order in the physical maps (published reference genomes of A. thaliana and A. lyrata) was compared with the marker order obtained from our F2 population. Two inversions (black circles) were identified. A few markers located on chromosome one of the A. lyrata genomic reference appeared reversed and translocated in the middle of chromosome two in our genetic map (gray circle).

(B) and (C) The translocation between chromosome one of the A. lyrata reference genome and chromosome 2 of A. arenosa is confirmed by the karyotypes of F2 individuals carrying altered number of copies of A. arenosa chromosomes 1 or 2.
