The claim is not verified by the U.S. as to their being an actual DNA relationship.
A DNA relationship is not necessary for one to be the “legal father”.
If Barrack 0bama Sr. is listed on 0bama’s BC; he is 0bama’s “legal father”.
You misspelled Barrack 0bama Sr.
He spelled his name Barak Hussein Obama.
By the way, whoever counterfeit Obama’s COLB did the same. They misspelled the name of Obama’s (alleged) father.
On the COLB, the (alleged) father’s name is spelled:
BARACK HUSSEIN OBAMA
The number of flaws in that document is staggering.
