F2 hybrids, the result of self or cross pollination of F1s, lack the consistency of F1s, though they may retain some desirable traits and can be produced more cheaply, because hand pollination or other interventions are not required. A Punnett square can be used to show the expected offspring from two parental groups with known genotypes.
