Fighting Cocks Genetics - back crossing

If you want to be a breeder of fighting cocks, genetics is very important. If you are a breeder, you must understand what is genetics. There are many types of breeding system that you can adopt in breeding fighting cocks, and examples of this are in-breeding, line breeding / back crossing, cross-breeding, and out-crossing.

In-breeding means you breed full sister and full brother, for example, your brood cock is grey and your brood hen is hatch then, your breed their offspring it becomes in-breeding because you breed the full brother to his full sister. Line breeding means, you breed father to his daughter or mother to his son. For example your brood hen is round-head and your brood cock is butcher, then their offspring is breed back to her mother, that is line-breeding. Cross-breeding means breeding of different bloodline. For example, your brood cock is butcher and your brood hen is round-head, the output of your cross-breeding is butcher-roundhead. Out-crossing means breading of the same bloodline coming from different sources. For example, you have a Dom brood cock, then you purchase another Dom brood hen from another breeder and then you breed them, the output of that is out-crossing.

Here is a complete example of back-crossing or line-breeding. Let assume that you have a round-head hen and you cross it with butcher cock. The offspring of this is ½ roundhead and ½ butcher (50% roundhead). Next, you breed their offspring which is ½ roundhead and ½ butcher back to his mother, and the offspring become ¾ round-head and ¼ butcher (75% roundhead). Then the offspring which is ¾ roundhead and ¼ butcher is breed back to his mother, the offspring will be 1/8 roundhead and 7/8 butcher (87.50% roundhead). Then the offspring which is 1/8 roundhead and 7/8 butcher will breed back to his mother the offspring will be 1/16 roundhead and 15/16 butcher (93.75% roundhead).
