With all due respect, these "resemblances" are all subjective opinions. The most important of them is the resemblance - if any - between BHO Sr. and the man who now calls himself BHO II. Does BHO II bear a resemblance to BHO Sr., close enough to think that about 50% of BHO II's DNA comes from BHO Sr.? From the photos we've seen, many, if not most of us, don't think so. But again, it's a subjective opinion. The only scientific way to tell for sure is DNA comparisons, and such a study would be practically impossible at this point in time.

It’s not unusual for children to resemble a grandparent more than their actual parents. It would be interesting to see photos of Obama Sr.’s parents. Sibling, or half-sibling, similarities do count for something, though as you said, exactly how much is entirely subjective. DNA is the only dispositive indicator.
How about Valery Garret as Obama’s half sister ? ... nothing is out of the realm of possibilities with this guy.
