And how do you mark color genetics? Or is it worth marking?
Noting the base genetics isn't necessary, it's just something some of us use to help breed for specific colors. Each horse has two alleles (letters) for each color gene, one that it inherited from its mother and one that it inherited from its father. So when you see something like E/e that means that the horse has a dominant copy of that gene from one parent and a recessive from the other. When that horse breeds it can pass one or the other of those two alleles to its offspring, but not both.vihar20032003 wrote:http://www.horseworldonline.net/horse/profile/879392
Some colors are easier to determine the genetics of than others. For example, if we grab a plain chestnut horse from the AC we know that its genetics are:Gray - G or g - Determines whether or not a horse is gray. A horse that is homozygous recessive (g/g) is not gray. A horse that is either heterozygous or homozygous dominant will always be gray (G/g or G/G). Gray covers all other colors, but does not appear at birth. Instead it spreads slowly throughout the horse's lifetime, usually starting with "goggles" around the eyes.
Extension - E or e - Determines whether or not a horse is red-based. A horse that is homozygous recessive (e/e) will always be red-based (chestnut, palomino, cremello, etc). A horse that is heterozygous or homozygous dominant will be black-based and may have bay, brown, or black as its base color (E/e or E/E).
Agouti - A, A+, At, or a - Determines whether a black-based horse is bay, brown or black. A red-based horse (e/e) will not be affected by the agouti gene. This gene is a little more complicated than extension or gray. A horse that is homozygous recessive (a/a) will be black-based. A horse that is At/At or At/a will be brown. A horse that is A+/A+, A+/At, or A+/a will be wild bay. A horse that is A/A, A/A+, A/At, or A/A will be bay.
Champagne - Ch or ch - Determines whether or not a horse expresses the champagne gene. A homozygous recessive (ch/ch) horse will not express champagne. A horse that heterozygous or homozygous dominant (Ch/ch or Ch/Ch) will display the champagne gene.
Dun - D or d - Determines whether or not a horse expresses the dun gene. A homozygous recessive (d/d) horse will not display dun. A horse that is heterozygous or homozygous dominant (D/d or D/D) will display the dun gene. Dun turns chestnut into red dun, bay into bay dun, brown into brown dun, and black into grullo/grulla.
Silver - Z or z - Determines whether or not a horse expresses the silver gene. A homozygous recessive (z/z) horse will not display the silver gene. A horse that is heterozygous or homozygous dominant (Z/z or Z/Z) will display the silver gene. The silver gene only affects black pigment, so a red-based horse will not show the silver gene even if it carries it.
Flaxen - F or f - Determines whether or not a horse expresses the flaxen gene. A homozygous or heterozygous dominant (F/f or F/F) horse will not display the flaxen gene. A horse that is homozygous recessive (f/f) with a chestnut base will display the flaxen gene. Flaxen is not apparent on black-based horses, or chestnut horses that carry visible cream or pearl dilutions.
Mealy - Pa or pa - Determines whether or not the horse displays the pangare gene. A homozygous recessive (pa/pa) horse will not display the pangare gene. A horse that is heterozygous or homozygous dominant (Pa/pa or pa/pa) will display the roan gene.
Roan - R or r - Determines whether or not a horse displays the roan gene. A homozygous recessive (r/r) horse will not display the roan gene. A horse that is heterozygous or homozygous dominant (R/r or R/R) will display the roan gene.
Tiger Eye - T or t - Determines whether or not a horse displays the tiger eye gene. A homozygous recessive horse (t/t) will not express tiger eye. A horse that is heterozygous dominant (T/t) will not display tiger eye unless it also has at least one copy of dominant champagne. A horse that is homozygous dominant (T/T) will always express the tiger eye gene.
Cream and Pearl - N, Cr, or prl - This is a dilution gene. It interacts with a horse's base color. A horse can be N/N, N/Cr, N/prl, Cr/Cr, Cr/prl, or prl/prl. A horse that is N/N or N/prl will show no visible effect to its coloration. A horse that is black and is N/Cr will show no visible effect to its adult color, though will appear slightly gray as a foal (this is called smoky black). N/Cr turns chestnut into palomino, bay into buckskin, and brown into smoky brown. Cr/Cr turns chestnut into cremello, bay into perlino, brown into brown cream, and black into smoky cream. Cr/prl turns chestnut into palomino pearl, bay into buckskin pearl, brown into brown cream pearl, and black into smoky pearl. And finally prl/prl turns chestnut into apricot, bay into bay pearl, brown into brown pearl, and black into black pearl.
Sooty - Sty or sty - A horse that is homozygous recessive (sty/sty) will not display the sooty gene. A horse that is heterozygous or homozygous dominant (Sty/sty or Sty/Sty) will display the sooty gene, though the degree of sootiness varies from horse to horse.
Arabian - gray, chestnut, bay, brown, black - Arabians will NEVER carry champagne, dun, silver, mealy, roan, tiger eye, cream or pearl.
Belgian - chestnut, bay, black, flaxen, mealy, roan - Belgians will NEVER carry gray, champagne, dun, silver, tiger eye, cream, or pearl. They also can not be brown.
Caspian - chestnut, bay, brown, black, dun - Caspians will NEVER carry gray, champagne, silver, mealy, roan, tiger eye, cream, or pearl.
Forest Horse - chestnut, bay, brown, dun, mealy - Forest Horses will NEVER carry gray, champagne, silver, roan, tiger eye, cream, or pearl.
North African Barb - all except gray - Barbs can be absolutely color EXCEPT for gray.
Przewalski Horse - ALWAYS mealy bay dun
Shetland Pony - all except pearl or gray - Shetlands can be any color EXCEPT gray or pearl.
Tarpan - ALWAYS bay dun
Turkmene - chestnut, bay, brown, black, dun, cream - Turkmenes will NEVER carry gray, champagne, silver, mealy, roan, or pearl.
