Count again. We have two cromosomes each (one from father, one from mother). Each chromosome has (during part of the cell cycle) two chromatids. That makes 4 alleles. From practical point of view we do have two alleles (one in each chromosome), but with point mutation and couple of billion truckloads of (bad) luck, we may talk about 4 different alleles. Yes, I'm nitpicking - no hard feelings, eh? :-) Ari-Matti -- -------------------------------------------------------------------- Ari-Matti Saren at the Institute of Biotechnology, Helsinki, Finland E-mail (on Internet): saren@operoni.helsinki.fi, Tel +358 0 434 6094 S-mail (home): Ohjaajantie 18 A 2, 00400 Helsinki, Finland ----------------Shikisoku - Zeku, Kusoki - Zeshiki------------------
