Question: Hank bears no resemblance to his father, but strongly resembles his mother. Bobby bears no resemblance to Hank (or seemingly Peggy), but bears a strong resemblance to Hank's father. Is it actually possible for a person to bear such a strong resemblance to one of their Grandparents if they are only getting half their genes from that Grandparent's child and that child bears no resemblance to that particular parent?

Chosen answer: The short answer is "yes", it is possible to resemble your Grandparent even if your parent doesn't resemble your Grandparent. The old adage is "it's not like mixing paint", meaning combining genes doesn't always get the same result. It's why full siblings don't always look exactly alike even though they have the same genetic makeup. I look next to nothing like my paternal grandmother but I have a child that greatly resembles her.
Is it a mistake then that Hank's Japanese half-brother strongly resembles him, and by extension Hank's mother, or is that still a small possibility?
Sort of. These are animated characters, and the style of animation isn't particularly detailed. The resemblance between the two is played up for laughs. But there are plenty of real life examples of people that aren't related at all but greatly resemble one another. Famous examples are Jeffrey Dean Morgan and Javier Bardem, or Will Ferrell and Chad Smith.

Answer: It's also said genetics plays a part here. You can look like an ancestor more than a parent. I myself look nothing like either of mine nor do any of my 3 siblings: older brother, older sister, younger sister.
