Exception to the law of inheritance Mendel

A group of geneticists from Purdue University in Indiana (USA), claims to have found in the plant Arabidopsis the corrected version of a defective gene inherited from their parents. Specifically, the plant was a carrier of two mutant copies of the gene, which allegedly was believed hitherto been impossible to have a normal offspring.

The researchers analyzed the mutated gene known as Hoth or exalted, for which the plant is not defective opened their flowers, and found that it had changed in 10% of the specimens that reproduced. It is as if a roofer.

in its genome, which has not yet been able to decipher, had retrieved the correct sequence in their genes. If confirmed the discovery, would be a rare exception in the laws inherited enunciated by the father of genetics, the Austrian monk Gregor Mendel in the nineteenth century.
