Black Solid Goats in the Red/Black/Brown Pool of Colored Angoras

Black goats in the R/B/B pool:

Black goats can range from true black, to gray to light silver. Solid colored goats are also referred to as "no pattern." Solid black goats can range from true black, to gray to light silver. Usually they are born with a black birth coat and then often fade to a lighter color as their mohair grows in. Goats that keep true black in their mohair as adults are less common. 

Solid black/gray goats are present in both the black/pattern pool and the red/black/brown pool, but each pool gets it's color differently. In the red/black/brown pool, the color is from genes on the Extension locus; black is the most dominant gene on the Extension. If there is a black gene here, black will be expressed. The other genes are red which requires 2 red genes for red to be expressed, and wild which does not express a color, but allows the color on agouti locus to be expressed. in the black/pattern pool it is on the agouti locus. It is impossible to tell what pool they belong to simply by looking at a solid black/gray goat. Looking through the pedigree to see what colors and patterns are present is the easiest way to make an educated guess as to which pool they get their color from. Another way is to breed the animal to a goat from either pool and see what color is produced in the kids.

Breeding black goats with genetics from the red/black/brown pool genetics to any of the colors in the red/black/brown pool should produce color which can be any shade of red, black or brown. Often one twin will be red and the other black. Breeding the same goat to a black/pattern pool goat will likely produce white kids.

Red Angora Goats in the Red/Black/Brown Pool

Red Angora Goats:

Red Angora Goats are common in the Red/Black/Brown pool of genetics. They can range from faded red, where they are born light red and fade to white as their mohair grows in, to deep, dark reds. They tend to fade some from their birth color, this tendency can vary. The color can be different shades of red on the animal. These goats can have any of the white spotting patterns over their primary red color. Occasionally a red goat may have black spots.

The Red/Black/Brown pool is also known as the "dominant" pool because the genes in this pool can mask the expression of color that would otherwise happen because of genes in the black/pattern pool. The genes for this color are located on the Extension locus.

Breeding a goat to another goat with genetics from the red/brown/black pool should produce any of the three colors. Be sure to know the pedigree of a black goat to make sure they have r/b/b pool genetics.

Red Black Brown Pool:

The Red/Black/Brown Pool (R/B/B) gets is color from genes located on the Extension locus. This color locus is more dominant than the Black/pattern pool agouti locus. Goats in this pool are typically a shade of red, black or brown as the name describes. The black often fades to gray. These goats are usually a solid color, but may have some variation of the shade of that color in their fleece. They do not have the predictable patterns present in the black/pattern pool. White spotting patterns do occur in these goats (in the black/pattern pool as well), but that is controlled by a different set of genes.

A goat having the right genes on the Extension locus will express that color, even it is has color genes on the Agouti locus that would have given it a black/pattern pool color. There are 3 genes for color on the Extension locus. Black is the most dominant, if 1 black is present, with red or wild as the second gene, black will be expressed. Red needs 2 red genes to be expressed. Wild does not express color, but opens up the opportunity for color genes at agouti locus to be expressed. This is the reason the R/B/B pool is also known as the dominant pool. The goat does need to get the right Extension genes from both parents to show color, so these genes are not dominant in the usual genetic sense where 1 dominant gene expresses the trait.

Reading through the pedigree is the easiest way to see which pool (or the potential for both pools) the goat will likely produce color with. For the R/B/B pool, look for these colors in the pedigree. A predominance of these colors increases the likelihood that the goat will produce color when bred to another goat in this pool.

Reds, blacks and brown goats can produce any of the 3 colors. Genetically, brown in the red/black/brown pool is actually a shade of red. 

Brown goats in the Red/black/brown pool can be differentiated from brown goats that get their color from the Brown locus by checking for black fibers. The Brown locus changes normally black color in a goat to a shade of brown, so no black will be present on a goat. R/B/B pool browns will typically have black hairs somewhere on their body. These hairs can be found in the fleece on some goats, but are easiest to see on the tail, legs and face. Presence of black hair shows that the goat is in the red/black/brown pool, because black can not be present on a brown locus goat. However, the inability to find black hairs does not prove that the goat's brown color is from the brown locus. At this time, brown angora goats are most likely a shade of red. The best way to eventually prove that a goat gets brown color from the brown locus would be to have a reverse badger where the black areas are instead a shade of brown. (brown or tan at the normally light white area does not qualify.) Toggenburg dairy goats are a good example of brown locus brown goats.
