Should be allowed to marry their siblings?

The short answer is no, incestuous marriages should not be allowed. There are many health risks and social issues associated with marrying a close relative and, accordingly, it is generally not permissible. However, some jurisdictions allow marriage between second cousins or more remote relatives, depending on local laws.
