Scheme of the evolution of Prunus and Fragaria chromosomes from an ancestral genome. Model of evolution of Prunus (PG1–PG8) and Fragaria (FG1–FG7) chromosomes from a hypothetical ancestral Rosaceae genome with x = 9 chromosomes (A1–A9). Only major chromosomal rearrangements (fusion/fission or translocation events involving more than two common markers between the two genomes) have been considered.
