The Agouti gene has three variable | The Agouti gene has three variable Alles. Agouti is the most dominate followed by Tan, and then Self is the most recessive. | ||
Agouti | Agouti locus's - expresses the "wild color" which is the banding of the individual hairs. Agouti is the most Dominate of the three Alleles present on Gene Marker "A". Agouti presents as individually stripped hairs , with bands along each hair shaft. This will create a color ring when you blow into the coat. Standard basic Agouti colors are Chestnut also called castor, sandy, copper ,ect depending on what breed you are referring op portion of the Rabbit , and the Solid color of the pheomelanin on the bottom. | ||
A few Color Patterns that are tan based are ,Tan, Martian, Otter. | |||
Their is a third loci on this gene. "a" is the most recessive Allele on the "A" locus, in order for it to be expressed it has to be Homozygous which mean both alleles on the gene have to have the recessive "a". If the animal has two recessive alleles it will have a solid colored hair shaft. If any other Allele from the "A" locus is present it will dominate the "a" and cancel it out. | |||
The "aa" locus expresses itself as a "self" colored rabbit, a "self " colored rabbit is as usually solid color rabbit that is expressive it's base color as controlled by the B locus , and sometimes modified by the D and "e" locus which we will cover in detail later. Some examples of Self colored rabbits , are Black, Chocolate, Lilac, Blue, and Tort rabbits. | |||

The Extension gene has five separate markers that control the extend of the band of an Agouti rabbit. Ed dominate black the rabbit will appear self as it will extend the color at B to entire hair follicle, Es steel is the second most dominate color, this extends the color at the B loci almost to the tip on an agouti rabbit, so the follicle will be soil 3/4 of the way to the tip with just the tip showing a red/yellow/white coloring. , E-regular extension, this will preset the hair as it is, and Agouti rabbit will have banded color along the hair shaft, and a self or tan rabbit will have a soil hair coloration. ej-Japanese harliquen is a co-dominate recessive gene that expresses patches of alternating color, or Bridling on Agouti coats. ee-is non-extension, it is the opposite of dominate black and hide the color at B on Agouti rabbit extending the tip color to the base . and blocking out all Eumelanin. | The Extension gene has five separate markers that control the extend of the band of an Agouti rabbit.
