a with b out of c, and then a with c out of d, and then a with d out of chicken called back to blood. Cousin matches can only be close relatives.

To A for the purpose of back to blood, then A + B out of the small cockfighting to choose the most representative of A's offspring C, at this time C accounted for 50% of A's pedigree, and then A + C out of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the offspring of the most representative of the offspring of the offspring of the offspring of the offspring of A E, E accounted for 87.5% of A, and so on. 87.5%, and so on and so forth.

Eventually a sample cockerel that most closely resembles A is produced, and this is a method used to maintain and perpetuate the A breed. Because many good cockatiels are about to leave their owners with age and the realities of fighting, the only way to leave their best traits behind is to backcross them. This is a long process, requires a lot of work and a lot of experience to screen and grasp, otherwise it is futile to return to the cross without grasping it!!!!

The cockerel only mates "father to daughter" and "son to mother" in the inbred mating method called "reverse mating method". For example: the breeder's female fighting cock gave birth to a very good male fighting cock, and he wants to have more of the same type of fighting cock, then he will match this male fighting cock with his mother, leaving the excellent little hen in the born chicks, and then use these hens to mating with their fathers in reverse, using this "inverse mating" to give birth to chicks very close to their fathers. The chicks born by this "reverse mating method" are very close to their fathers. What is even more noteworthy is that there is no serious degeneration in the reverse mating method. The cock obtained by this method is of great benefit to the breeder. He is able to pass on all his good qualities to the next generation in a strong and powerful way. What you see him as, that is what his future chicks will look like.

Pedigree chickens also tend to be the most defective chickens 。。。。。 But it's possible to come up with genetically exploded chickens Pedigree chickens are actually technically no better than A-blood and A-blood crossbred dog chickens

Purified chickens have equally prominent advantages and defects, and crossbreeding with purified chickens hides the defects, while the advantages are inherited dominantly.

This is the fundamental reason why the formation of strains must be purified.

1. Inbreeding = the chickens from male 1 and female 1, and then mated with them, the chickens are called inbreeding

2. Inbreeding = the chickens from male 1 and female 1 and the chickens from female 1 are called inbreeding, which means that the chickens from the same nest are mated with each other.

3, blood relatives = male 1 and female 1 of the offspring of each other (in addition to the same father and mother of the same chicken and the same nest of chickens) or male 1 with a different hen born of the offspring of each other and then mated with each other is called blood relatives.

4, half-origin blood = two bloodlines of close relatives back to the blood or two bloodlines of close relatives of the blood of the chicken produced by the match is called half-origin blood.

5, strong strong blood = the strongest chicken and the strongest chicken match produced chickens, or the best chicken and the best chicken produced chickens (regardless of blood lineage and pedigree), but preferably with pedigree and blood lineage.

6,The rooster's genes make up the XY chromosome and the hen's genes make up the XX chromosome. The Y chromosome of the rooster in the offspring is from the father and the X chromosome is from the mother. A hen in the offspring has two X chromosomes, one from the father and one from the mother. Genes only produce mutations, and the chance of mutation is low for a single individual. Mutations (which means changes) in genes are random and can occur in any situation and in any chicken.

Inbreeding is common in fighting chickens
