This reminds me of the mechanisms the penguins used in the book "The Selfish Gene" by Charles Dawkins to make sure their genes get passed on. It shows that penguins relatives if they did not have kids benefited by raising and protecting their nieces and nephews because they still contained some of the same genes.

It's Charles Darwin but Richard Dawkins! :)
There are many examples. Think about eusocial insects, for example bees, where two 'sisters' have more genes in common than 'mother' and 'daughter'. That's one possible explanation why they sacrifice themselves for each other.
