Vance stared at him, his eyes narrowing. "Are you?"
"Your mother," Vance said, glancing at the portrait of the late Mrs. Blackwood hanging above the mantle, "was Type A. It is possible she had an affair with a man who carried the O gene. But Arthur? He was ruled out the moment you were born."
Elena crossed her arms. "I fail to see the issue. If he was AB, he could pass an A gene. I could be his." blood type pedigree mystery
Let me know and I can add those. Like this post? Save it for your next genetics lesson. 🧬🔎
"You claim Arthur is your father," Vance said softly. "But scientifically, it is impossible. An AB father cannot have an O child. You, sir, are not a Blackwood." Vance stared at him, his eyes narrowing
Typically, blood types A and B are inherited separately from each parent. In this "paradoxical" inheritance, parents with types AB and O can unexpectedly have children who are either AB or O , which normally seems genetically impossible.
"Do you?" Vance asked. "Blood type follows strict genetic rules, Mr. Blackwood. A person with Type AB has both A and B antigens, but no O. Therefore, an AB parent can never, under any circumstances, pass an 'O' gene to their child. They can only pass an 'A' or a 'B'." It is possible she had an affair with
: The paper "An unusual case of blood group ABO inheritance: O from AB X O" details a Japanese family where an O-type child was born to AB and O parents. Unlike Cis-AB, this was caused by a rare structural mutation during the formation of the egg (oogenesis).
