Black Silver

Black Labrador Retriever - Silver factoring or mixed?

A black Labrador retriever, the factor of money with a coat that is slightly less than black, is claimed by some as a purebred dog. Reportedly rare and highly desirable, one silver black Labrador Retriever, as factors that may be proposed at a price higher than normal. Is it worth it? Or is it simply a crossing - a mongrel?

Black Labrador Retriever Standard

The standard of the breed Labrador Retriever, said: "The color layer Labrador Retriever are black, yellow and chocolate. Any color or combination of colors is a disqualification. "Standard of the breed is to say that black Labrador must be entirely black. If a black Labrador has a white patch on the chest is" acceptable but not desirable, "according to the breed standard.

A black Labrador retriever, the money factor or not, must comply with this rule. Each Black Labrador Retriever must be black.

Genetically

A black Labrador retriever, the money factor or disagree with the rule, apparently genetics that are not compatible with race. The genetics of coat color of a true black Labrador Retriever seem fairly simple. Each dog receives two pairs of genes: one from the mother and father.

Remember at the beginning of science class that there are two types of genes in all beings living are dominant and recessive. It's your case, and even the black Labrador Retrievers. Genes determine the color of hair, such as genes determine the color of the fur of a black Labrador dog. You may have brown, black, red, blonde, or a variant of one of them. A Labrador Retriever has only two options: dark chocolate and chocolate - but we see black and yellow.

Consider these facts.

1. In the Labrador Retriever, a dominant gene will always determine the coat color. Forever. No matter what other genes are present. The black gene, which we call "B" for short, is predominant. Therefore, if a "B" gene is present, the pre-selected coat color is black. But read on.

2. Call it the recessive gene for chocolate "b" for short. The "B" genes can produce a layer of chocolate, if the dog is not hereditary "B" genes. These are the only options, "B" key genes and black "B" chocolate recessive genes. Over there a gene from yellow to silver or other colors. A key factor Labrador Retriever black, silver or other would have to go against this genetic composition.

3. In addition to genes and dark chocolate Labrador Retriever other two genes. These genes determine the ability of dogs to express a mantle dark, namely to show dark. Call of gene expression dominant "E" for mail short and to the expression of recessive genes "for short.

4. Labrador Retriever with the dominant "E" of genes are able to express a dark coat. Perhaps black or chocolate. If the dog is a "B" genes and "E" gene, which is black, no matter what other genes it has. If you "b" and "E" of genes to be chocolate.

5. Labrador Retriever who have the "e" recessive "gene can not show a dark coat. Blacklist or chocolate. It will show the absence of them is a yellow tone. A Labrador Retriever with a combination like Bbee has 2 dominant genes for black, but the recessive "e" genes will not allow the spectacle of color. The yellow dog.

You'll see a black Labrador Retriever, The money factor is not possible with these pairs of genes. There is no scientific data to date (2007) found no gene that money black Labrador Retriever.

The true nature of what is called Silver Labs

A black Labrador Retriever is said that money may be a factor unusually light yellow or chocolate lab. There is also the United States, a brown-gray, like that of Weimaraners. It is reported that the kennel of the United States First "Silver" Labradors also held Weimaraner, a breed of silver-gray with a little similar. We generally believed that the true nature of a black labrador retriever, money factor is a junction: Labrador Retriever - mix of Weimar.

The AKC recognizes the "silver" Labs, like chocolate, and rejects them because they do not meet breed standards for laboratories chocolate. A black Labrador Retriever is no money factor is a dog breed AKC standard.
