Prolonging life: remove the paternal genes!

Geneticists explain the prolongation of life in the "daughters of two mothers" by the suppression of the Rasgrf1 gene on chromosome 9 inherited from the father. It is possible that other genes, usually transmitted from the father, also affect life expectancy.
