Analyzing Trait Variance
20. Quantitative Genetics / Analyzing Trait Variance / Problem 3

Two inbred lines of wheat (W1 and W2) produce different average grain yields per plot. The mean yield (pounds) and the variance of yields in different generations are as follows:
Table showing mean grain yields and variances for inbred wheat lines W1, W2, F1, and F2.
What is the phenotypic variance (VP) for grain yield in this case?
