text: Re-analysing data from seven populations across four continents, Fox and her colleagues found that grandmothers’ effects on grandchildren varied according to their X-chromosome relatedness: paternal grandmothers, who are 50% X-related to granddaughters, were most beneficial to the survival of their granddaughters but least beneficial to the survival of their grandsons, with whom they share zero X-chromosomes.
