The horses in Horse Reality consist of various characteristics. Each horse consists of +/-50 genes. All of them together determine which colour the horse is, how healthy it is and how it performs in shows and competitions.

All characteristics are divided into 4 groups, and each characteristic consists of 2 alleles:

  • Colour genetics: to determine the colour of the horse
  • Phenotype (conformation): used to determine scores in competitions and horse shows
  • Genetic Potential: used to determine scores in competitions
  • Health: used for breeding and the general health condition of horses

Colour genetics

Most of the colour genetics are available after testing. Be aware that you can only test genes that have tests available for them in reality. Let's take flaxen as an example. There is no test available for flaxen in real life, which means that you cannot test for flaxen in Horse Reality either. Even though there is no test available for it, you can still see it on the horse as blonde manes and tail. Which means that there can be some hidden genes that you don't know of. Make sure to keep an eye out for it.

The phenotype of a horse is used to determine how good-looking and moving the horse is. When you go to a horse's achievements page and check it's conformation, you get a global view of those statistics.

At the moment of writing, the phenotype statistics are divided into 5 groups:

  1. Poor = < 40 points
  2. Below average = 40 - 59 points
  3. Average = 60 - 69 points
  4. Good = 70 - 84 points
  5. Very good = 85+ points

When you enter your horse in a horse show, your horse will be tested on several traits: posture, head, neck, back, legs, socks, walk, trot, canter, gallop. When entering in a horse show, there will be a few extra things to take into account. You can find more information about it here.

Genetic Potential

There are 22 genes that determine a horse's genetic potential. In order to keep it a bit simple for players, we've combined them into 6 traits.

  1. Speed
  2. Agility
  3. Jumping
  4. Stamina
  5. Power
  6. Balance

Each trait consists of about 2 to 6 different genes, both consisting of 2 alleles. When you breed your horses, they will always pick 1 allele of the dam and 1 allele of the sire for each gene. Depending on which one, it could be that the outcome of your foal has a completely different genetic potential than you expected.

Inheritance example

For example, the speed trait has 3 genes, so 6 alleles in total. If your dam has, for example, the numbers: 50/65, 54/70, 45/49 for the speed trait. The total average for speed would be: 55,5% ( (50+65+54+70+45+49) / 6).

If the sire has: 70/80, 84/83, 39/78. His average for speed would be: 72,3% ( (70+80+84+83+39+78) / 6). Your foal has tonnes of opportunities. If you have bad luck, he could get the lowest scoring alleles of both parents which would give the foal the outcome of 56,8% ( (50+54+45+70+83+39) / 6). However, if you're very lucky, he gets the best of all of them. That would give the foal a 71% average ( (65+70+49+80+84+78) / 6 ) for speed.

We can imagine that it's hard to understand all of this, which is why we wanted to make it visually a bit simpler in the game than how it's really working. The easiest part to get is that if the average number is very high, both alleles should be pretty close to each other. Let's take 100 to make it easy. If your horse has a 100% average for speed, the horse MUST have all alleles on 100% since (6 x 100) / 6 is 100%. If you keep that in mind and put high numbers together each time, the upcoming foal is most likely to get a similar score as its parents.

All inherited alleles can get a few extra points or a few points are taken away in order to keep a bit of variation within horses and to make them better (or worse).


At this moment, health is not really taken into account yet. The only part where health is checked is when you are breeding with your horses.

Miscarriages and early embryonic deaths

All mares will have a 5% chance of a miscarriage after a breeding within a few days. In reality, 80% of mares deliver a fully grown foal, while 20% loses the embryo, fetus or foal during the pregnancy. For now, we implemented a chance of 5% for ALL pregnancies, no matter if the mare is healthy or not. Even healthy horses can lose their embryo.

The other factor we've taken into account, is the quality of the stallion's semen. Depending on what his stats are, the chance of a failed pregnancy gets higher.

These are the current stats:

  • 80+ quality = chance +5%;
  • 65+ quality = chance +10%;
  • 50+ quality= chance +15%;
  • 25+ quality= chance +20%;
  • <25 quality= chance = 40%;

This means that if you would have a mare bred with a stallion that has good semen. The total chance of a failed pregnancy is 10% (you have always 5% chance + 5% extra because of his semen). This means you have a 90% chance of getting a healthy foal out of this combination, and it is still 10% lower than the official birth rate in equines.

A failed pregnancy happens when you breed with a horse with bad semen. After 2 days of "pregnancy", you will receive a message that your mare doesn't seem to be carrying an embryo and she isn't pregnant. After these days you can breed her again. Normally you find out in approximately 40-50 days if your mare is or isn't pregnant anymore, which is why you receive the message 2 days after the breeding.

A miscarriage happens due to that 5% chance we started with. This will happen after 4 days of "pregnancy". It means that she started to have a foal, but she lost it after 4-5 months of her pregnancy.

Both issues result in the same notification for now. At a later stage, we will implement different notifications with the real explanation. For now, you will receive a message that states your mare doesn't seem to carry an embryo and that she isn't pregnant anymore.


Like said, these characteristics aren't displayed or used in the game yet (besides semen quality). But just to give you this upfront information, those are the ones you might want to improve by breeding. The better your horse's health will be, the fewer problems it will have.

  • Health
  • Semen quality
  • Colic
  • Hooves
  • Back Problems
  • Respiratory
  • Lameness
