In the study published in Thursday's issue of Journal Nature, scientists produced mice with one normal and one abnormal gene, by giving the subjects white patches on tail.
After observing subsequent breeding and a new crop of mice, the scientists to their surprise found that 24 out of 27 of the baby mice inherited the trait without actually having the gene.
Repeated breeding with mice with even normal set of genes also led to the similar results.
Researchers found that the RNA molecule was carrying the hereditary signal which was earlier supposed to be limited to just DNA.
Scientists believe that the finding can one day understand aspects of diabetes, infertility and other problems.
