I have watched this discussion for a couple of days and thought it had gone far enough so you would not mind me splicing a request in. I am involved with a closed email group which is currently discussing the salvation of wild populations of killifish. We are all killikeepers and want to know things like, "How many fish of a wild strain are needed to begin a species maintenance effort to stack the deck in favor of keeping phenotype, if not genotype, stable from F0 thru FX (where X= infinity)?" One of our number has written a program in C to model hypothetical species maintenance efforts. I would like it to be a bit better at dealing with traits which are not simply dominant/recessive. When "values" for a given gene exceed 2 the program gives what I feel are misleading results. Basically the program has a random number generator which causes output file to show "loss" of genes (alleles?) much sooner than I would expect. It just settles on one value that after several generations, is shown to be the only value left. Does anyone have a simple program written in C which might better deal with this genetic problem? An algorithim is probably sufficient. It is hoped we can spearhead a worldwide program to preserve these and other fauna, and good models will help lay groundwork. jeff
