Evolution de la variabilité génétique inter et intra-populations de populations de Salmonidés issues de mêmes pools géniques
Through electrophoretic analysis of 14 enzymatic systems corresponding to 31 loci, we studied the change over six generations in the intra- and inter-population variability of salmonid populations from the same initial genetic pool. Four collections of brook trout (Salvelinus fontinalis) and five of...
