Dividing a childless grandfather's intestate property, among his grandsons.

Besides the Jewish/Israeli law, is there any other legal system in which:

The childless grandfather's intestate property - is divided UNEQUALLY among his three grandsons - if, one grandson has no siblings - whereas the other two grandsons are full siblings.


(The Jewish/Israeli law - gives a half to the grandson who has no siblings - because, he represents his dead parent who - would have inherited a half - if the grandfather's two children had been alive).
