Regarding grand father property

Hello sir, greetings of the day. 
A grandson has rights on his grandfather's ancestral property by birth. The death of his father or grandfather has nothing to do with this fact. Since birth, the grandson owns a share in his grandfather's property already. The distribution of property is done in such a way that each of the shares further gets divided into successive generations. If no will is present to justify the inheritance then in that case, A grandchild can inherit their grandparent's property only when their parent through whom they are related to that grandparent has died before that grandparent. If such a case arises, the share of the grandfather's property the parent in question would have inherited if they were alive will be divided amongst the mother, provided she is alive and the grandchild and their siblings. The shares would be equally divided among the siblings, and the mother. Where all the siblings will both get equal shares. The distribution of the grandfather's property among his grandchildren depends majorly on the type of property his grandfather had. 
Hope this answers your query.
