Examples of these include early marriages, sororate marriages, inheritance, polygamy, and appeasement of avenging spirits, lack of education, gender violence and lack of exposure (Mapuranga, 2010).
Others that are less widespread include dry sexual intercourse, sororate marriage practices (where a deceased wife is replaced by her young sister) and levirate marriage practices (where a man marries his deceased brother's widow).
Customs like levirate and sororate, by which a widow lives with the younger brother of her husband and a man marries the younger sister of his wife, show that marriage is very much a relationship between families rather than between individuals.
