A schematic showing the group marriage relationship. The picture illustrates that 4 types of relationships are possible (male-male, male-female, female-male, female-female), between each of the involved persons in the marriage scheme. The dotted lines means that more parties can be added to the scheme.<br>
Note: The arrows between the symbols only connects one symbol on each side. I.e. 1 male (or female) symbol with 1 male (or female) symbol.
