The weedy cress has challenged the Mendelian inheritance theory, which is central to genetics. The plant, known as Arabidopsis thaliana, is able to inherit DNA from previous generations that were not present in its parents, which is theoretically impossible. Robert Pruitt's team at Purdue University in the US discovered that cress carrying two mutant copies of a single gene is able to correct the DNA that is passed on to the offspring. The researchers believe that the genes RNA templates inherited from previous generations are responsible for correcting the mutant genes.
