During our entire lives, everyone always noticed how alike my brother, my father, and myself looked. As a teenager, friends of my brother, who had never seen me, would on occasion spot me on a bus (or something), and ask, "excuse me, but are you [his name]'s brother?" In terms of body type, we are (or were, my father is dead now) all mesophorphic, with my brother and father inclining a bit more towards ectomorphic. In terms of things like lips, nose, ears, etc, there isn't really any meaningful difference. There is arguably a difference in skull structure, with mine being more towards "cubic" than theirs, which is more elongated; consistent with their being more into the ectomorphic side.
My father's father looked, again, remarkably like my father, and so like my brother and I; the difference being that he seemed to be still more ectomorphic-ish (btw he died before I was born).
Regarding types: I am LIE, my brother is ILE, my father was SEI. According to an aunt of mine, who got to know us both, my personality is very much like my grandfather's, and from what I know of his life, LIE makes sense.
So, we have a LIE who had a SEI son, who then had ILE and LIE sons. All of whom looked pretty much alike in those kinds of features.
Now, it may well be that even those differences in facial features that we had could still be connected to type; but, if I'm correct in typing my grandfather as LIE, even the body type does not help much there.
I know that this example isn't very helpful if I don't provide pictures of us all; but my point is that, to me, that already makes me rather skeptical of VI according to those kinds of features.
ETA: correcting typo, I has written "SEI" instead of "LIE" at one point.
