Estimation of the heritability of isoprenoid levels
To identify the fraction of the observed variation that is genetically
determined, we estimated the broad sense heritability
(H2 ) for each isoprenoid (Table 1) as described
in the Material and Methods section. In the AI-RIL population, the broad
sense heritability ranged from 0.33 (for Phytosterols) to 0.55 (for Pren
and Dol) and 0.57 (for Tocopherols) (Table 1).
