Reply #23: Nepal, I believe, has a polyandrous minority

Families with multiple sons take one wife for all the sons. It's the way they keep the family land together, instead of cutting it up into small parcels for each son when the parents die. The wife is expected to go down the line, starting with the eldest, having offspring for each son. It's an old institution but it works about as well as anyone familiar with male jealousy issues thinks it would.
