The pattern of kinship among the various groups varies in accordance with accepted behavior which is to some extent expressed in kinship terminologies. An individual is reckoned to be equally related structurally to his parentage from both sides although behaviorally his interactions with such individuals may vary in accordance with the social distance built between them. Thus, he may relate himself more to either side depending on this interaction bias in terms of social organization. Behavior-wise, kinship is cognatic as has been noted in the northern mountain groups. In southern Philippines, where Islamic religion has been entrenched, a lineal-like organization is resurgent that is somewhat segmentary in nature.
