Well, I think you're quite right, Amos. I agree that it is "a mistaken belief to feel you are achieving some fraction of immortality simply because you have combined your chromosomes with another and sent the genotype forward."

I've never believed in that myself. I know my father and his parents believed in it very strongly, so he must have been quite perturbed that I had no children in this life.

Since I figure I'm going forward anyway (as a living spirit), I'm not too worried about passing any of my genes on to secure "immortality".
