I am trying to get a consensus on this question: Is the term 'F1 generation' reserved solely for the heterozygous offspring of pure-breeding parents as in Mendel's experiments, or can it be used to name the first generation of offspring from any known parental cross? Is this like the old folks calling all denim jeans Levi's, even though Levi's is just one of many brands. People commonly refer to 'the F1' in the first way and others know what they mean, but is one always the other?

The letter F used to designate generations from parental is actually short for filial, defined on google as: designating the generation or the sequence of generations following the parental generation It doesn't matter what the genotype of phenotype of the offspring fo the P generation are, they are always the F1 generation.
