potential errors in Figure1a Oori Weisshaus, Nrgene Ltd 22 January 2015 If I understand correctly Fig 1a: by Gen2 the chromosomes should each contain two colors (AB/CD) and not as depicted. that would require another generation of recombination. also :depicting the chromosomes as rice seeds (instead of conventional lines or actual chromosome shaped) is needlessly confusing... unless I got it all wrong, and you intended to relate to seeds and not to chromosomes.
