Mouse finding violates known laws of heredity

Science & Technology at Scientific Mouse Finding Violates Laws of Heredity
In experiments with mutant mice, Minoo Rassoulzadegan of Inserm in France proved that in the case of a trait regulating the coloring of fur on toes and tail of mice, the coloration did not conform to mendelian laws of heredity. It seems that the mutant mice’ RNA, which the mice bear unusual levels of, played a role in bringing out the recessive white patch fur trait in mice which had two copies of the dominant brown fur trait.
Exactly how the RNA is doing this remains a mystery, but it does put a challenge to the current prevailing theory that DNA is the sole final arbiter of heredity from a molecular point of view.
