An individual Thoroughbred cannot have more than two different alleles for each gene locus, one on each chromosome.
How many alleles are available at a certain gene locus is variable based on what the gene controls and how many alleles are available and their frequency in the population.
The answer for Howrse is Chestnut and Bay
the answer is Bay and chestnut for howrse and for reality
Yes, cremello horses are rare as they result from a specific combination of genes that produce a light cream coat color, blue eyes, and pink skin. This coloration is less common compared to other coat colors in horses.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Depending on how they got identical genes, they may be clones (if it was done artificially, and they were born at different times), or if they were born at the same time, they could be identical twins. However, I don't think horses ever have twins.
A number of breeds of horses have the Creme gene which produces buckskin, palomino and smokey black in the Crcr (heterozygous) state and Perlino, Cremello and Smokey Creme in the CrCr (homozygous) state. Thoroughbreds, Quarter Horses, Morgans, Welsh Ponies, miniature horses, POAs, Appaloosas, Lusitanos and many of the warmblood breeds have the dilution genes to produce buckskins.
Black is a colour, not a breed. Colours originate from genes which the horse receives from its parents.
they have all inherited traits like their eye color or their color of their fur
In the USA there is only one breed called Paint, that is the American Paint Horse, whose parent registry is the American Paint Horse Association (APHA). All other part colored horses are pintos.Other breeds may carry the pinto genes/ patterns, but are not considered Paints as they do not come from Paint horse stock. For instance Gypsy Vanners ( also called Gypsy Cobs, Tinker horses, and colored cobs) carry the pinto genes, but are not Paints.
Red (AKA chestnut) and Black. In the related links you will find a page that can tell you a ton about the red and black genes, as well as how they work with other genes. *Note: it says Morgan horses, but it goes for all breeds*
That all depends on genetics and what genes the 2 horses have. Cannot give you an exact answer unless the horses are homozygous for the color gene they have. You can breed 2 horses of the same color and make a completely different color.
Bay (light, dark...) and Grey (looks white) Actually, the two main color genes for horses is chestnut (red) and black. All horses- regardless of what other genes they have (creme, roan, etc.)- are either chestnut (red) or black at their base color. Not bay and grey. You can see the site in the related links explains all about the base colors, and what modifies them into other colors, like bay or grey. It says Morgan horses, but it goes for all breeds.
