The term come from usa. It make sense for wild caught cac. For hybrid, it is kind of confusing. F0.5 I saw some breeder use.

F1 mean Ferrari, Mercedes, Red Bull

Seems like the claims to be F1 is of a higher quality.

Default Mendelian genetics term

https://en.m.wikipedia.org/wiki/F1_hybrid

An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types.[1] F1 hybrids are used in genetics, and in selective breeding, where it may appear as F1 crossbreed. The term is sometimes written with a subscript, as F1 hybrid.[2][3] Subsequent generations are called F2, F3, etc.

The offspring of distinctly different parental types produce a new, uniform phenotype with a combination of characteristics from the parents. In fish breeding, those parents frequently are two closely related fish species, while in plant and animal breeding the parents often are two inbred lines. Mules are F1 hybrids between horse and donkey. Today, certain domestic–wild hybrid breeds, such as the Bengal cat and the Savannah cat, are classified by their filial generation number.

Gregor Mendel focused on patterns of inheritance and the genetic basis for variation. In his cross-pollination experiments involving two true-breeding, or homozygous, parents, Mendel found that the resulting F1 generation were heterozygous and consistent. The offspring showed a combination of the phenotypes from each parent that were genetically dominant. Mendel’s discoveries involving the F1 and F2 generations laid the foundation for modern genetics.
