I've already mentioned it. I was under the impression that each gene or combination thereof corresponded to particular biological structures and/or functions within an organism. Is that correct?
I apologise Jamest, this is a reasonable question to ask. As I understand it (and my understanding is poor and based on limited reading) is that there is a lot to do with how genes interact with each other and recombine, that explains the complexity of functions within the smaller number of genes that homo sapiens possess. I hope someone with more knowledge of this can come along and explain.
However, this explanation alone doesn't entirely address your further question of...

At a guess, I think it is because a lot of that genetic information is probably doing nothing. The gene sequence is not at the point of recombination and interaction between the different genes, to create more complex functions.
Hopefully someone better educated. etc etc
