Heritability of Directional Asymmetry in Drosophila melanogaster

Table 3

Realized heritability estimates (±S.E.) for DA obtained using four techniques. Data was either the single-generation values of selection differential and response or the cumulative ones. Heritabilities were calculated either with ordinary unweighted least squares (OLSs) regression or with a weighted generalized least squares (GLSs) regression.
