Should be allowed to marry their siblings?
<|assistant|>
In most cultures and jurisdictions, incestuous marriages between siblings are not permitted and are considered illegal. There are some exceptions to this, however, such as in some Latin American countries, which allow first-cousin marriages, and in some religious traditions such as Christian, Jewish, and Mormon, where incestuous unions are permitted up to the seventh degree of consanguinity. In these instances, all applicable laws must be followed and proper precautions must be taken, as the potential for genetic defects among offspring from these unions is extremely high.
