Dear Michael;
Thanks. I will not use these simulated data for any research. I will use the real data which did not come yet. I needed to simulate a data set and make my software ready before real data come. So this simulation kind of will be preliminary work before real. I am familiar with PROC INBREED very well but I could not simulate the pedigree structure as I posted to LISTSERV.
Once again thank for writing and humor,
Oslo

Oslo, nuclear families; random mating?!?!?! What the hey; this is a G-rated, or maybe even a PG-13-rated Listserv; not an R-rated one!
All kidding aside, this looks similar to a question that Mak had back on October 30th, concerning the dubiously named PROC INBREED. You can get more information on that particular procedure in the SAS Online documentation. Here is at least one link:
http://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/statug_inbreed_sect006.htm
...to get you started.
Man, oh man; I sure hope that I haven't just helped to enable some bizarre government research project--you know, like some sort of doomsday Noah's Ark or something!
Oslo, best of luck in all of your SAS endeavors!
I hope that this suggestion proves helpful now, and in the future!

I would not rule out the chance to preserve a nucleus of human specimens.
