Table 1. Impacts of parental aging and estimation of narrow-sense heritability on offspring traits in the Pacific oyster (C. gigas).
Table summarizes the main effect of maternal age, paternal age, and their interaction (−, negative effect; n.s., nonsignificant effect) on the F1 generation at multiple life stages, in larvae (2 to 40 days old), spats (40 to 365 days old), and young adults (>365 old; see timelines of sampling in fig. S2). It also reports the narrow-sense heritability (h2) values surrounded by the 95% confidence interval (CI).
