There's no denying it. The Uber strain bears too much genetic resemblance to Chryssalids for it to be a mere coincidence. It is inevitable to concede that Ubers are a crossbreed of Chryssalid and Human: human traits becoming turbocharged by Chryssalid's hellerium-powered metabolism. Since Chryssalids themselves are genetically related to Zombie Parasites they carry (most likely through genetic engineering), that makes Ubers related to Zombies as well.
