Genetic linkage maps for each of three hybrid species of Helianthus (data from Rieseberg et al. 2003). For a species’ map, the 17 linkage groups are plotted along with their designations. Portions of a linkage group that are white were inferred to have originated in H. annuus, and those that are black to have originated in H. petiolaris. Hash marks to the right of each linkage group indicate the position of informative markers (inferred parentage: H. annuus—gray, and H. petiolaris—black). Regions that were inferred to harbor junctions are indicated by transitions from black to white (abrupt or grayscale transition).
