The silver coloration comes into play when the D gene is turned on - which does not happen in labradors. If the D gene is dd then it will "dilute" the coloration if the B gene is bb in labradors. In other breeds the dilute combo (dd) can make a Bb or BB dog gray or "blue". A dog like the doberman has this dilute gene pattern and therefore "blue" dobies can arise from a black doberman that has this dilute combination. Other breeds like Great Danes, Chow Chows, and German Shepherds can be diluted. Some breeds accept the color and others do not.
The breeders of silver labs say that it is not the work of the D gene but of the B gene working in conjunction with the C gene which I don't think is true in Labradors - (C for "concentration" can cause fox reds in our breed when combined with ee and it can influence the concentration of black or chocolate expression as well - goes into why some chocolates are darker than others).
Nice plagerism! What you did is
