Are agnate and uterine real brother and sister?

Answer 1

agnate sibling: are the one that share the same father but not the same mother uterine sibling: are the one that share the same mother but not the same father i think that agnate slibling are far part brother nd sister blood b/c they dont share the same mother cause if you share the same mother then you close brother nd sister but dont share same father. uterine slibling are close blood brother nd sister b/c they share the same mother not the same father if you dont share the same mother but the same father then that not close brother nd sister.. so the best half sibling are the uterine sibling sharing same mother not the same father. by.
