Transfer Of Self Acquired Property To Adopted Son

Dear Sir, My actual biological father has adopted me to one of is relative, & now he is planning to transfer the property (land & house) self acquired by him through gift deed by paying stamp duty. If I get this self acquired land & house of my biological father through gift deed, will it be treated as a income to my biological father, & will he need to pay any tax to the government value for the land & house. Also he planning to give share in ancestral property, can this also be done through gift deed. if not, what is the best option to get the share on ancestral property from biological father for adopted son. Thank you
