Genetics

The Genetics tab is not available until your horse has been tested by Dorothea Dejardin.  This will require one medical plant and for you to ride the horse to Dorothea Dejardin.  The Genetics tab will tell you your horse’s coat phenotype, markings, and gene string.  The Gene String is based off of real horse coat color genetics.  The gene string has nothing to do with the horse’s stats so it is completely possible to breed for stats without using Genetic testing.

**Gene String**

The gene string is a collection of up to 8 genes.  Each gene is a pairing of letters which stand for the alleles.  Two alleles make up one gene.  The left side letter (allele) comes from the Dam’s genes.  The right side letter (allele) comes from the Sire’s genes.  If a letter is capitalized then the allele  is dominant. If the letter is lower case, then the allele is recessive.  The gene must contain one to two dominant alleles for a trait to be expressed.  The order of the alleles does not matter, simply the dominant vs. recessive.

When you breed a horse, either of the two alleles from the parent is randomly selected and combined with the allele from the other parent to form the foal’s gene.

Example 1:  Dam with gene A/A  + Sire with gene a/a could produce:

                               Foal with gene A/a only

Example 2:  Dam with gene A/a + Sire with gene A/a could produce:

                               Foal with gene A/A

                               Foal with gene A/a or Foal with gene a/A (same gene)

                               Foal with gene a/a

**Horse Coat Color Genes**

W Gene: True White Gene: lack of pigmentation gene. This gene is not listed in the game as of 1.1.4

E Gene: Base coat color. Every non- “true white” horse has a base coat color of Black, Bay, or Chestnut.

               Black genotype: E/E or E/e

               Bay genotype:  E/E/ or E/e

               Chestnut genotype: e/e

A Gene: Agouti Gene, distribution of black gene

               Black Agouti genotype: a/a

               Bay Agouti genotype: A/A or A/a

               Chestnut Agouti genotype: A/A, A/a, or a/a

**Coat Dilution Genes**

D Gene: the Dun dilution gene: D/D or D/d will produce horses with dun marking.  d/d will have no Dun markings.

               Bay Dun:  Bay base coat with dominant Dun gene

               Red Dun: Chestnut base coat with dominant Dun gene

               Grulla:  Black based coat with dominant Dun gene

Rn gene: the Roan pattern gene.  Not in game as far as 1.1.4

Ch gene:  the Champagne Dilution gene: Ch/Ch or Ch/ch will produce champagne horses.  ch/ch will not be champagne.

Cr Gene:  Cream Dilutions

               cr/cr: No cream dilutions

               Cr/cr  with Bay base: Buckskin

               Cr/cr with Chestnut base: Palomino

               Cr/cr with Black base: Smoky Black

               Cr/Cr with Bay base: Perlino

               Cr/Cr with Chestnut base: Cremello

               Cr/Cr with Black base: Smoky Cream

**Any Base Coat Genes**

Lp Gene:  Leopard Complex Gene.  Lp/Lp or Lp/lp will express Leopard coat; lp/lp will not

G Gene:  Grey (progressive depigmentation of the hairs) G/G or G/g will express Grey coat; g/g will not

To Gene: Tobiano. To/To or To/to will express Tobiano coat; to/to will not.
