Teaching Arabidopsis Genetics

David Meinke et al presented a superb poster at the recent Plant Genome I.
In it he described the mapping of a large number of embryo-lethal mutations
using, in part, a set of well marked strains. I suggest you talk to the
people at the Arabidopsis Stock Center (arabidopsis+ at osu.edu), I believe
they have the complete mapping set. These could be the basis for a fine
exposition of diploid genetics, together with some "unknown", or unmapped,
