The Genetics of Coat Colors in Dogs

The genetics of coat colors in dogs is a complex subject, but can be broken down into a few basic principles. The first step is to understand that each dog has two copies of every gene, one from each parent. Genes come in different forms, called alleles. For example, the gene for coat color can have two alleles, black and brown. Dogs inherit one allele for each gene from each parent.The next step is to understand how genes are expressed. Genes are expressed when they are turned on, and the amount of expression can vary. For example, the gene for coat color can be turned on to a greater or lesser degree, resulting in a dog with a black coat or a brown coat.Finally, we need to understand how genes are passed down from generation to generation. Genes are passed down in a predictable manner, called Mendelian inheritance. This means that each gene is passed down independently of the other genes. For example,

The Role of the MC1R Gene in Dog Coat Colors

The MC1R gene is responsible for the production of a pigment called eumelanin. Eumelanin is responsible for the black and brown colors in dog coats. Dogs that have a mutation in the MC1R gene will not produce eumelanin and will have a white coat. The MC1R gene is located on chromosome 6. Dogs that have a mutation in the MC1R gene will have a white coat. There are several different mutations in the MC1R gene that can cause a white coat. The most common mutation is the R72Q mutation. This mutation changes a protein called melanocortin 1 receptor (MC1R) into a protein called melanocortin 1 receptor-like (MC1RL). This mutation prevents the receptor from working properly and causes a lack of pigment in the coat. Dogs that have a mutation in the MC1R gene will not produce eumelanin

The Role of Other Genes in Dog Coat Colors

There are a variety of genes that control the color of a dog’s coat. The genes that are most commonly talked about are the B and K genes. The B gene codes for black pigment, and the K gene codes for the absence of black pigment. Dogs that are BB or BK will have a black coat, while dogs that are kk will have a white coat. There are also a number of other genes that can contribute to a dog’s coat color.The A gene codes for the production of the red pigment, and the E gene codes for the production of the yellow pigment. Dogs that are Aa or Ae will have a red coat, while dogs that are ee will have a yellow coat. Dogs that are AaEe will have a liver coat, while dogs that are aaee will have a black coat.The C gene codes for the production of the albino pigment, and the S gene codes for

Inheritance of Coat Colors in Dogs

The genetics of coat color in dogs is a complex subject, but can be understood with a basic understanding of Mendelian genetics. The genes that control coat color are located on different chromosomes, so they are said to be “linked.” This means that they are passed down together from parents to their offspring. There are two main genes that control coat color in dogs ” the B gene and the E gene. The B gene is responsible for the black coat color, and the E gene is responsible for the yellow coat color. Dogs that have two copies of the B gene will have a black coat, while dogs that have two copies of the E gene will have a yellow coat. Dogs that have one copy of the B gene and one copy of the E gene will have a liver (chocolate) coat color.The genes that control coat color are also dominant and recessive. This means that if a dog has a dominant gene for a particular coat color, that gene
