Thanks. I am a biologist, and rather new to the complexity language. Thanks for setting me straight.

Actually, Peter on further thought, If there are 2 alleles per locus (there are obviously much more) that means that there are 2^25000 possible combinations. My computers built in calculator returns infinity for that number. 2^64 is 18 quintillion. Now I am not sure how fast deep thought is, but this sounds like it is getting very close to a number that is too big to calculate.

Phylogenetics runs into this problem a lot when searching trees. They have developed sophisticated search algorithms, and we might well be able to come up with some that would give us a pretty good guess about what a gene “does” averaged across all possible genotypes. However, I am not volunteering to phenotype 18 quintillion organisms. . .
