Genetic update mechanism of chromosomes found Swiss researchers from the University of Lausanne in common frogs Rana temporaria, reports Rus.Media. The so-called “fountain of youth” allows sex change to avoid the degeneration of DNA.

As you know, people have a female X chromosome and male – Y. similarly in amphibians, including the frogs. However, unlike humans, these animals exhibit no signs of degeneration of chromosomes, degeneration of the Y chromosome. Scientists have found that this recombination occurs between the chromosomes. This leads to a change of gender, but allows you to maintain the condition of the Y-chromosome. Experts came to believe that the “fountain of youth” may be observed in other amphibians that can change gender.
