| The people of Spiti have a system of polyandry and primogeniture to combat the short supply of resources that are available in the raw mountains. |
| Polygyny and polyandry are not allowed, and it is forbidden to marry close family and kin members. |
| Thus the expectations regarding the strength of sexual selection for polygyny, polyandry, and monogamy are fairly simple. |
| Most marriages are monogamous, although fraternal polyandry is permitted and is even considered to be prestigious. |
| And in any case, polyandry is certainly not the ideal for Indian womanhood. |
| From then on, polygyny replaced polyandry as a marital practice. |
