Cousin marriages refer to the practice of individuals marrying their cousins, who are relatives sharing a common ancestor. This practice is common in various cultures around the world, including some regions in the Middle East, South Asia, and parts of Africa. The reasons for cousin marriages can include cultural traditions, family ties, and economic considerations. While cousin marriages can strengthen family bonds, they also raise concerns about genetic risks for offspring. Children born to closely related parents may have a higher chance of inheriting genetic disorders. As a result, some countries have laws regulating or prohibiting cousin marriages to address these health concerns.
