Daughter's right in a property owned by father recieved as 'will' from her grandmother.

My grandfather had bought a 25 acres land in 1947. After his demise it was owned by my grandmother. My grandparents had two sons, one my father and other my uncle. Before my grandmother's death she divided her property between her two sons by transferring all ancestral property to my uncle (elder son) and compensated my father by willing the 25 acres of self acquired land to my father. My father and I have had a falling apart and he threatens to disown me as well as will all his property to my brother. I understand that a property acquired by my grandfather and willed to my father does not fall in the category of ancestral property however since my father recieved this property in lieu of giving up his rights to any of the ancestral property belonging to my grandparents during inhouse partition between him and my uncle - has he not willfully denied me or his children the natural right to their grandparent's ancestral property? And if yes then would the said 'willed by my grandmother' property which he holds still continues to remain in the category of self acquired/non ancestral property vis a vis me? And I have no claim in either the ancestral property which in it's entirety has been passed on to my uncle or the 'willed' property which my father has recieved in lieu of giving up his claim on his share of the ancestral property?
