Mahabharata Anushasna Parva Chapter 49:2

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 49:2 "'Bhishma said, "The son of one's loins is regarded as one's own self. The son that is begotten upon one's wife by a person whom one has invited for the task, is called Niruktaja. The son that is begotten upon one's wife by somebody without one's permission, is Prasritaja. The son begotten upon his own wife by a person fallen away from his status is called Patitaja. There are two other sons, viz., the son given, and the son made. There is another called Adhyudha.The son born of a maiden in her father's house is called Kanina. Besides these, there are six kinds of sons called Apadhwansaja and six others that are Apasadas. These are the several kinds of sons mentioned in the scriptures, learn, O Bharata!" "'Yudhishthira said, "Who are the six that are called Apadhwansajas? Who also are the Apasadas? It behoveth thee to explain all these to me in detail. "'Bhishma said, "The sons that a Brahmana begets upon spouses taken from the three inferior orders, those begotten by a Kshatriya upon spouses taken from the two orders inferior to his own, O Bharata, and the sons that a Vaisya begets upon a spouse taken from the one order that is inferior to his,—are all called Apadhwansajas. They are, as thus explained, of six kinds. Listen now to me as I tell thee who the Apasadas are. The son that a Sudra begets upon a Brahmana woman is called a Chandala. Begotten upon a Kshatriya woman by a person of the Sudra order, the son is called a Vratya. He who is born of a Vaisya woman by a Sudra father is called a Vaidya. These three kinds of sons are called Apasadas. The Vaisya, by uniting himself with a woman of the Brahmana order, begets a son that is called a Magadha, while the son that he gets upon a Kshatriya woman is called a Vamaka. The Kshatriya can beget but one kind of son upon a woman of a superior order. Indeed, the son begotten by a Kshatriya upon a Brahmana woman, is called a Suta. These three also are called Apasadas. It cannot be said, O king, that these six kinds of sons are no sons." "'Yudhishthira said, "Some say that one's son is he that is born in one's soil. Some, on the other hand, say that one's son is he who has been begotten from one's seed. Are both these kinds of sons equal? Where, again, is the son to be? Do thou tell me this, O grandsire!" "'Bhishma said, "His is the son from whose seed he has sprung. If, however, the owner of the seed abandons the son born of it, such a son then becomes his upon whose spouse he has been begotten. The same rule applies to the son called Adhyudha. He belongs to the person from whose seed he has taken his birth. If, however, the owner of the seed abandons him, he becomes the son of the husband of his mother.Know that even this is what the law declares."
