In Nicotiana, two inbred strains produce long (PL) and short (PS) corollas. These lines are crossed to produce F1, and the F1 are crossed to produce F2 plants in which corolla length and variance are measured. The table summarizes mean and variance of corolla length in each generation.


Generation  Mean Corolla Length   Variance
PL                          85.75              4.21
PS            43.15      2.89
F1            62.26       3.42
F2            67.37      36.30

Calculate H2 for corolla length in Nicotiana.
