Is Marrying a Cousin Legal?
In many countries, marrying a cousin is legal, but rules vary by jurisdiction. Some U.S. states allow first-cousin marriage, while others restrict or prohibit it. Laws also differ across Europe, Asia, and the Middle East. Local family law determines what is permitted where you live.
What Are the Genetic Risks?
Children of first cousins have a slightly higher chance of inheriting certain recessive genetic conditions compared to the general population. The absolute risk remains low. Genetic counseling can help families understand specific risks based on health history.
Why Do Cousins Marry?
Cousin marriage is common in many cultures for social, economic, and family reasons. It can help preserve traditions, strengthen family ties, and keep wealth within a community. In some regions, it is a long-standing norm rather than an exception.
