    Looks like you are talking about filial generations:

    Offspring generation. F1 is the first offspring or filial generation; F2 is the second; and so on. Successive generations of progeny in a controlled series of crosses, starting with two specific parents (the P generation) and selfing or intercrossing the progeny of each new (F1; F2; . . . ) generation.

    The P generation is the 'parent' that's when you buy great stock out of some impressive line of some animal or plant.

    F1 would be the breeding stock's (the P generation) first decedents by blood

    F2 would be the breeding stock's second direct decedents, the direct decedents of two F1s

    F3 would be Great grands of F1, direct decedents of two F2s

    Quote:that is correct... there is also B1, B2 which stands for the first time breeding back to the Original P(parent line).

    I'm still learning on this too but for a good example, I think is the olive egg.

    First generation would be offspring from say a maran(dark egg layer) crossed with a blue egg layer (P). These eggs would be blue but the chicks that hatch will grow up and lay olive eggs (F1). Then you can cross the chicks that come out of these F1 eggs back to daddy maran and have chicks in the next generation (F2) that will lay even darker eggs.

    I think I got that right. Someone tell me if I'm making this more confusing or I'm wrong [​IMG]

    This is what I use. Please excuse me if I repeat information. Some of what I will post is found elsewhere in this thread.

    P = parent

    P X P = F1 ( first generation produced by crossing parents)

    F1 X F1 = F2 ( the generation produced when two F1 are crossed)

    F2 x F2 = F3 ( the generation produced when two F2 are crossed)

    etc.

    P X F1= BC1 ( the first generation that is back crossed to the recurrent or also called back cross parent)

    P x BC1= BC2 (second generation that is back crossed to the recurrent or also called back cross parent)

    etc.

    F1 X BC2= BC2F2 ( second generation produced from a back cross 2 generation and F1 )

    BC2F2 x BC2F2= BC2F3

    etc.
