There is a broad resemblance of type if not detail. The head shapes are similar, rounded with pointed chins. They share the tendency of female cartoon characters in general to have somewhat infantilized features -- round, oversized heads, large eyes, delicate nose and mouth. They're both rendered using the same technique, 3D computer modelling simulating realistic skin and hair texture on a caricatured frame. And they're both key-animated by hand rather than motion capture, performed by American animators trained at Disney and/or Pixar, so there are probably similarities in character movement and performance (not evident in still images) that arise from that similar training, just as actors who are veterans of the Royal Shakespeare Company tend to share similar speech rhythms and performance styles.
So no, it's not as if they look a great deal alike, but when watching Rapunzel, I did feel reminded of Elastigirl to some extent, both in the general structure of her head and facial anatomy and in the way her face was animated. Which is good, because as I think I've said before in this thread, the character animation on Elastigirl was a magnificent piece of work. And so was Rapunzel. (I wish it were easier to find credits for these things. I know Glen Keane was the lead animator on Rapunzel, but who did Elastigirl? Maybe if I had time right now to search through the special features on my Incredibles DVD I could find out, but the Internet isn't helping much.)
