Genetics are a complete mystery to us. How can some siblings look so much alike while others don’t even look like they’re from the same family tree — let alone the same branch?

Take, for example, Blake Jenner (Ryder), whose brother Richard recently tweeted this picture of the two of them together.

“Me and the baby bro on my last trip to Los Angeles,” the caption reads. “Finalizing my next trip right now!!”

We definitely wouldn’t have figured these two were bros if we hadn’t been told otherwise!
Blake isn’t the only Glee star who doesn’t look much like his brother: Darren Criss and his brother don’t have a very strong resemblance, either, but like Blake and Richard, they’re super close!
