Ok so basically: there are currently three genes that determine Labrador coat colors. These genes each have two variations called alleles. The first of these is the pigment expression allele denoted as an “E”. The capital letter shows the dominate trait for genes. Lower case is recessive. In the case of labs there is no intermediate variation in the “heterozygous” case which would be “Ee” for this allele. Instead we call these labs to be carriers of the recessive trait without showing that they have the trait. Anyways, back to the “E” trait. When a dog has the “E” trait that means that they will express either brown or black coloration (we are not looking at the dilute factor yet). If instead both the maternal and paternal alleles give the dog an “ee” inheritance the dog will always be yellow in color. Meaning that the recessive “homozygous recessive” for the pigment trait will breed yellow labs. The second trait for lab coloration is the brown or black coloration. Now that we understand the pigment expression we look at the variations of brown and black. Black is dominate to brown so as long as there is a “B” present that dog will be a black lab. So to recap- a “EEBB, EeBb, EeBB and EEBb” will all give you a black lab. “eeBb, eeBB and eebb” will be yellow labs and “EEbb and Eebb” will be chocolate labs. The additional variation is the dilute gene. Like the yellow coloration- the color is only expressed if both genes are recessive “dd”. So now that we know if they will be yellow, black or chocolate we can add the dilute trait to the mix. Yellows will the homozygous recessive (both lowercase) will be red or white labs, blacks will be charcoal, and chocolates will be silver labs. There is a lot of controversy on lab color and if these dogs are actually true labs. The answer is absolutely. But at first these variations are very rare- as breeders start to breed dogs that randomly express these color changes they select for those colors in the population. They can at first happen as a random mutation which is very common and happens to all organisms. The more we breed these dogs the more we see them in the population. For example, when labs were first breed there was only the black coloration. Many generations later the yellow labs showed up then chocolate. Now we have dilute genes in the population showing the evolution of Labradors throughout history. Hope this answers your question.
Wild is 110% spot on. The AKC has ruined more field dogs than they will ever create. Thank GOD the pointing dog world has American Field...... I’m hoping Brittany’s will completely split from the AKC after the last debacle I’ve had with them. The AKC is a joke for those of us in the pointing dog world, who actually want dogs to point and run vs look good in a show ring based on a “standard”.
So my daughter is into gentics ....it's over my head she said this is the simple version of it.

Tagging. I have a fox red out of Morgan’s kennel in Chewelah. Interesting read. There is a graphite colored dog that works at SeaTac that is absolutely gorgeous. Anyone seen him? I asked the handler if I could take a picture but he failed to stop and pose for me.
Is there any difference in other areas physically or any temperament issues known to be with these "non pure" colors? Not trying to be a jerk or anything just curious about it.

AKC has never written a breed standard or promoted a style. It is your own breed club. If you know and research how the AKC works, you find they are a registry and the individual breed clubs handle the rest. March on....
