Elopement often arranged by parents, demonstrating bravery and maintaining family relationships. However, endogamous marriages in Merariq families can lead to health issues and genetic disorders. Among them, 75% of participants were admitted to endogamous marriages among relatives, and some parents forbid their children from marrying relatives due to guilt.
