Inheritance
Maybe your great-great grandmother will be of use to you after all. Geneticists examining Arabidopsis mutants focused on revertant offspring - that is, offspring of double-mutant parents that mysteriously revert to ancestral (unmutated) form - believe that the plants are somehow inheriting genes from ancestors beyond their parents. Previous researchers have just assumed that revertant plants were due to errors or contamination, but this group looked at them. This is so freakin' cool!
