Explanation:

- "Dudhlantana" is a term related to bride wealth or compensation for not marrying a person one is expected to marry according to customary rules.

- Among Gonds, there is a tradition where if a person does not marry their cross cousin (who should be their preferred spouse), some form of compensation called “Dudhlantana” may be paid.

- The Santhals do not have this specific custom. Their marriage practices are different and do not involve "Dudhlantana."

- The Nayars (or Nairs, from Kerala) follow a matrilineal system and do not practice cross-cousin marriage nor pay "Dudhlantana."

- Among the Bhils, this particular tradition is also not found.
