Final answer:
Affinal kin are related through marriage or mutual agreement, while consanguineal kin are related by blood. Affinal ties can be broken, while consanguineal ties are permanent.
Step-by-step explanation:
Affinal kin are individuals who are related through marriage or mutual agreement, while consanguineal kin are individuals who are related by blood. The main difference between the two is the basis of their relationship, with affinal kin being connected through legal or social ties, and consanguineal kin being connected through biological ties.
For example, if a person's aunt is their mother's sister, then the aunt would be their consanguineal kin. On the other hand, if a person's uncle is their father's brother, then the uncle would be their affinal kin.
It is important to note that affinal ties can be broken through divorce or other means, while consanguineal ties are generally considered permanent.
