What is the F2 generation. Give an example

1 answer

The F2 generation refers to the second generation of offspring resulting from the mating of two organisms, usually plants or animals, that are both F1 generation hybrids.

For example, if a tall pea plant (TT) is crossed with a short pea plant (tt) and all of their F1 offspring are tall (Tt), then crossing two of these F1 offspring plants would produce the F2 generation. In this case, the F2 generation could contain a mix of tall and short plants, following the predictable 3:1 ratio of Mendelian genetics.
