Check out photos of his supposed grandfather when he was a young man. Notice the ears. I think Grandpa may actually be the father. Obama has supposedly referred to him as his father on a couple of occasions. It’s just not right that we have to be speculating like this.
You missed the rather noticeable fact of complexion and went with the ears? LOL
If Grandpa were the father, a remarkably evidence-free assertion, then BO would be 100% white.
Per the ears, BO has 25% of his genetic material from Gramps, assuming the family tree is as specified. Plenty to account for ear shape.
