`  :First of all, you have provided no cite that Beta Israel are ``genetically the same``, so that would be OR unless you can.  Secondly, even if you did have a source, it would be disputed / contested, because neither tribes recognises that they are ``genetically the same``.  Secondly, Amhara is not a genetic affiliation.  The are several unrelated tribes who all adopted the same language and religion, ie , Ethiopian Orthodox.  Any tribes like the Beta Israel (who have their own language) are not Amhara; the word Amhara in Ethiopia is virtually synonymous with Orthodox (of course not entirely since there are also Orthodox non Amharas, thise who speak other languages)...  Even the so called ``Muslim AMharas`` are not regarded as fully Amhara, but go by a different name.  All of this is sourced, try reading ``The Ethiopians`` also ``Wax and Gold``.    `
