It always amazes me how they say that no two snowflakes are exactly the

fallen from the sky, that would be ludicrous, however, I feel it must be
based on some mathematical theory. This has similarities to a calculation
I did at GCSE Biology which showed why no two people look alike, was to do
with genotypes and chromosomes IIRC.

I think "alike" should be "identical" - there are plenty of people who
look alike. I've seen that I have at least a couple of doubles. Once I
was watching tennis on TV and saw myself in the crowd, and another time
someone showed me a newspaper picture of a group of people at a CAMRA
meeting. There was I, pint in hand as usual, but I couldn't remember the
occasion - then realized that was because it wasn't me.
