F1 hybrid
F1 stands for “first filial generation.” The F1 generation is the first generation of offspring produced by a set of parents. Many gamefowl breeders use the term F1 to mean as the first generation of offspring produced by imported parents. The term F1 has become popular among game fowl raisers, more specifically among chicken peddlers on the internet. Many sellers advertise their gamefowl as F1 in order to sell at a better price. However, F1 simply stands for first filial generation. Therefore, all chickens are F1s in relation to their parents.
Don’t get confused. The truth is F1 could mean so many things. So when you encounter the word F1, don’t take it by the definition you know, instead ask the breeder, seller or peddler, as the case may be, what exactly he means by F1. And, don’t be surprised if some don’t even have a definition to give, as they used the term without any clear cut understanding of its meaning.
By denotation, an F1 is not necessarily a pure or a cross. F1 is a generation resulting immediately from a set of parents. So, depending on your point of reference, every generation is an F1 in relation to its parents. So in this respect, every individual cock or hen is an F1.
On the other hand, the term “F1 hybrid” in genetics is never pure. It is the first filial generation resulting from a cross between strains or breeds of distinct genotypes, thus it is a crossbred. Do not mistake hybrid with “high breed” or “hi-breed.” The former means a cross between distinct bloodlines while the latter is a term Filipinos use to refer to a game fowl of high quality.
Hybrid is the offspring of two animals of different breeds, varieties, species, or genera, usually produced for specific genetic characteristics. In gamefowl breeding hybrid is being used to mean a cross between breeds or strains.
An F1 hybrid, in genetics, is the first filial generation of offspring parents belonging to distinctly different breed or types. An example of an F1 hybrid in gamefowl breeding is a cross between an aseel and an American or American and Peruvian.
In gamefowl breeding, the term F1 is more appropriately applied to the first generation battle crosses as results of outcrossing of two strains such as a roundhead x hatch.
We at RB Sugbo also use the term F1 for the first of a series of generations that leads eventually to creating a new strain. An example was our SBF1 or the Shuffler Blakliz F1, winning-wise a very successful generation that lead to our new strain the Shuffler Blakiiz.
We use the term F1 when we refer to a cross that will be further used for continuity or link matings, not a terminal cross or a simple battle cross. To us one definition of an F1 is a cross with further breeding purpose.
