Filial by definition meaning "denoting the generation(s) after the parental generation"
I dont know how f1 wouldnt mean a first generation hybrid? Please explain.
I suppose you could dumb it down, but terminology is important.
F1 hybrid defined:
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] 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 genetics the parents usually are two
inbred lines.
Mules are F1 hybrids between
horse and
donkey. Today, certain domestic–wild hybrid breeds, such as 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.
