Understand the genetics of horse color. - split-ridge farm rocky mountain horse
I was fascinated by the colour when I saw my first "chocolate horse". Also I was bewildered by the different colour concepts and what was special about "no talk gene"? Have you ever wondered how you could have a chocolate horse without a genetic predisposition?
Decided to find an answer and to continue my education, I threw myself into the intriguing world of colour genetic science. I want this page to be a simple colour gen-scrash course for the mediocre Joe (like me!) who is eager to know the fundamentals. While there are many different strains that monitor colour in many different races, I will only discuss some of the fundamentals of the Rocky Mountain horse here (if you want to know what a colour horse is, you need to read a little more yourself!).
They have two base colourigments in all races - blacks and reds. Darkness dominates reds. A number of genetics exist that thin colours and other genetics that limit where the dye can build up on the human being. Horse have a number of "color genes" in their Dna.
You have two photocopies of each colour and each horse parentage will give one copy to its descendants. Thus a filly receives a copy of mum & a copy of papa for each genetic couple on its colour chromosome. 3. But the easiest way, as I was told, is that each colour couple could have one or both seeds switched on or off.
The ON (or dominant) nature of the horse can influence the colour of the horse. There is no effect on colour if the genetic material is OFF (or recessive). Once both seeds are OFF - the colour of the horse is not affected and this colour is not transmitted to the descendants of this mother.
When one of the two pairs is ON and the other is OFF, the horse colour is affected - so it is sufficient if one of the two pairs is ON to edit the colour. Since the horse only passes on one of the two to its descendants, you may or may not get a filly with the ON-Gen.
Horses with ON and OFF genetic are regarded as "heterozygous" for this colour. Once both are ON, the horse is regarded as "homozygous" for this colour and you have the guarantee that it will give this colour to your newborn. However, the first gen under consideration is the "extension" gen and is indicated by the character "e".
It is this group of genes, when ON (E) allows the formation of dark pigments on the human organism - this is the so-called dark one. Once this is OFF, (e) it inhibits the formation of dark pigments - only the dark pigments remain - it is called the bright orange one.
The horse appears dark if a horse has a lone dark genetic and a dark genetic (Ee), because blacks dominate reds. That' a horse in blacks with a genetic predisposition to redness - he can either cast a colt or not. This means that he does not have a central genetic and cannot reproduce a human colt - even if the colt has a central genetic from the other parents, he is still assured of a central genetic from that parents and therefore cannot be a human colt even though it is carrying the genetic.
Next to be considered is the agouti gen (or bay gene) and is symbolised by the character "a". It is a restricted genetic and only affects the pigments of the horse's blacks, limiting them to the horse's points (legs, head, back and around the mouths / strings / ears). An ee horse with the agouti genes would not be affected at all.
An EE or Ee horse with the Agouti genes would have limited the dark pigments to the dots so that the horse's bodies would leave a reddish-brown hue and the horse would be referred to as a bay. So you can have a horse without a EE (red gene) that seems to have scarlet haired - it is just a case that the scarlet pigments cannot develop and leave a scarlet outline.
Schokoladenpferde: Silver Dapple Gen (Z) is a thinning agent that only affects dark coat and has a more intensive thinning effect on rough coat of male and female tails than on bodily coat. That' what gives the Rocky Mountain Horse its chocolate colour.
No effect from a horse in blood with the golden one. There is a chocolate horse with a silvery genus and the colour of the horse's head and tails ranges from flat to cream. That means that a horse that has two replicas of both the dark and silvery seeds (like our Maple) will always have a chocolate filly if no other diluting seeds are added that influence it.
Chocolate horses can also be described as silver-coloured blacks. EDWARD: EDWARD: Red Chocolate Horses: It is a horse in chocolate that bears the Bay (Agouti) Gen and the Silvery Gen. With the Agouti genes, the blacks are limited to the dots and the blacks are then reduced by the Dapple genes to a chocolate/flax colour.
Also known as the Silberbucht is a chocolate horse. Another diluting agent is the crème gen and is symbolised by the letter "Cr". It is different when one is ON than when both are ON. If only one creaming agent is switched on, it only thinens reddish coat - so a reddish horse with a creaming agent would be a calomino, a brown horse with a creaming agent would be a suede.
However, a horse with a crème gen otype is regarded as smoke and looks no different from a normal crème, but some say that they are sometimes more pale or slightly burned into a brighter shadow. Switching on both creams will affect both white and brown coat as well as complexion and eyes.
The Perlinos (Bay/Double Cream) and Cremellos (Red/Double Cream) have two different creams. Blacks with two creams Genen is a smoke Creme. Horse with two creams are brightly coloured and can be hard to tell what they are without using a test for blood samples (Perlino, Cremello or smoke cream). Maple has a crème strain that matches both its crème strain Schwarz (black) and its crème strain Silber (silver smoke black) - it is known as chocolate crème.
She will ALWAYS have chocolate filly if she is raised with a male colt in either dark or dark colour. Cultivated with an agouti genome, it can also make either chocolate or suede. Whilst your main pedigree areas in Rocky Mountain Horse pedigree are spirit, exterior and gang, it's great to study colour pedigree and forecast what each crossing will do.
So if you want to learn more about horse colour genetic and about other colour genetic (like Roan, Dun, Champagne, Grullo, Gray, etc.) I have put together a few pages which I think are quite interesting and understandable.
