I'm not a biology person but I think everyone except identical twins has different DNA which makes the problem so much harder since "doing it once" only solves one person's problem when every variable (dna) can potentially interact with every other (n^n problem where n = 3,000,000,000 potential pairs which is an insane number, granted it almost certainly has some defined structure which reduces the potential differences but that will still be a huge number) . Also, you have the whole nature versus nurture problem which makes biology even harder.

Even identical twins are not all that identical. Reading and understand the DNA is one thing, reading and understanding the regulatory network that controls which genes are expressed under what circumstances is at least as difficult.

As an identical twin we have 99.99% the same DNA. But after conception you have epigeneic factors that will start to play. Or even the fact that we don't live the same lives. For instance I like doing math for fun. My brother doesn't care for math at all really.
