Chapter 19, Problem 12P

Two inbred lines of sunflowers $\left({\text{P}}_1{\text{ and P}}_2\right)$ produce different total weights of seeds per flower head. The mean weight of seeds (grams) and the variance of seed weights in different generations are as follows.

a. Use the information above to determine ${\text{V}}_{\text{G}}{\text{,V}}_{\text{E}}{\text{, and V}}_P$ for this trait.

b. Determine ${\text{H}}^{\text{2}}$ for this trait.
