crossbreeding

 

what is crossbreeding ?

A horse is a thoroughbred (only one breed in his origins)
or a crossbred (more than one breed in his origins).

You can see the breed of a horse looking at his origins chart.


On the origins chart, you can't have more than 5 breeds >

(even if your horse has more than 5 breeds in his origins,
only the 5 breeds with the higher % are represented in the chart. The other breeds are not anymore in the origins chart)

Total of breed % is 100%

 
 

How are the % breeds calculated ?

It's the average of the parents breeds

For one breed :
Foal's % Breed = (Mother's % Breed + Father's % Breed) /2

 

If the father doesn't have a breed of the mother :
Foal's % Breed = (Mother's % Breed) /2

If the mother doesn't have a breed of the father :
Foal's % Breed = (Father's % Breed) /2

 

If a breed has less than 1%,
it dissapears from the origins chart
(so it's possible to make a thoroughbred by crossbreeding
several times a crossbred horse with a thoroughbred horse)

technical infos

example :
Father
Breed A = Paint Horse 50%
Breed B = Appaloosa 30%
Breed C = Welsh 20%

Mother
Breed A = Paint Horse 50%
Breed B = Quarter Horse 40%
Breed C = P.S.H. 10%

Foal
Breed A = Paint Horse 50%
Breed B = Appaloosa 15%
Breed C = Welsh 10%
Breed D = Quarter Horse 20%
Breed E = P.S.H. 5%

 

Example of crossbreeding

Looking at the breeds of the foal :
- 3 breeds have dissapeared :
Thoroughbred
Appaloosa
Newfoundland pony

- The breeds % have been recalculated so that the total of %
is still 100%

(i.e. by the right calculation, the Quarter Horse % should have been 25%)

 

reproduction rules for 50/50 breeds

If you breed 2 horses, of any breed, but :
50% breed A
50% breed B

like this horse : 50/50 Foal

Her breed is : Hanoverian = breed A
but in her origins, you can see :
50 % Hanoverian = breed A
50% Arabian Horse = breed B

 

1/. Father : breed A (origins 50% breed A / 50% breed B) + Mother : breed A (origins 50% breed A / 50% breed B)
=> Foal : breed B (origins 50% breed A / 50% breed B)

2/. Father : breed B (origins 50% breed A / 50% breed B) + Mother : breed B (origins 50% breed A / 50% breed B)
=> Foal : breed A (origins 50% breed A / 50% breed B)

3/. Father : breed A (origins 50% breed A / 50% breed B) + Mother : breed B (origins 50% breed A / 50% breed B)
=> Foal : breed A (origins 50% breed A / 50% breed B)

4/. Father : breed B (origins 50% breed A / 50% breed B) + Mother : breed A (origins 50% breed A / 50% breed B)
=> Foal : breed B (origins 50% breed A / 50% breed B)
 

Example of 50/50

Breed A = Connemara
Breed B = Arabian Horse

Father : breed A
+
Mother : breed A

=> Foal : breed B
