Under patriliny, the social system that traces descent through the male line, the primary claimants to a father's resources when he dies are his sons. This is because patriliny emphasizes the importance of male heirs and their ability to carry on the family name and lineage.

Explanation:

- Patriliny: Patriliny is a social system where descent is traced through the male line. In such societies, the male lineage is of utmost importance, and the inheritance of resources and property is typically passed down from father to son.
- Claiming resources: When a father dies in a patrilineal society, his resources, including property, land, and wealth, are typically inherited by his male children, particularly his sons. This is based on the belief that sons are responsible for carrying on the family name and lineage.
- Importance of male heirs: In patrilineal societies, male heirs are highly valued because they ensure the continuation of the family line. They are expected to marry and produce offspring, which will carry on the family name and maintain the ancestral traditions.
- Sons as primary claimants: Sons are considered the primary claimants to their father's resources because they are seen as the direct continuation of the family line. Inheriting their father's resources allows them to uphold the family's social standing, maintain economic stability, and fulfill their responsibilities as male heirs.
- Other possible claimants: While sons have the highest priority in claiming their father's resources, other male relatives such as brothers and grandsons could also be considered as secondary claimants, depending on the specific cultural norms and practices within the patrilineal society.
- Daughters' claim: Daughters, on the other hand, generally have a lower priority in inheriting their father's resources in patrilineal societies. This is because they are expected to marry into other families and take on new family names, thereby severing their ties to their paternal lineage.

In conclusion, under patriliny, the primary claimants to a father's resources when he dies are his sons. This is because sons are seen as the direct continuation of the family line and have the responsibility of upholding the family's social and economic standing. Other male relatives such as brothers and grandsons may also have a claim, but daughters generally have a lower priority in inheritance.

Sons could claim their father's property and the elder one get more.
