Table 4 Statistics describing the phenotypic and genetic variability for the estimates of Daphnia life history and phototactic response

From: An SNP-based second-generation genetic map of Daphnia magna and its application to QTL analysis of phenotypic traits

Trait Mean SD H 2 95% CI
Life history traits     
Body size (mm) 3.856 0.138 0.607 (0.542, 0.657)
Age at first clutch (days) 13.685 2.304 0.191 (0.130, 0.256)
Fecundity 159.367 56.297 0.505 (0.430, 0.569)
Phototactic response     
Presence of fish -0.503 0.386 0.439 (0.363, 0.500)
Absence of fish -0.104 0.331 0.416 (0.343, 0.481)
  1. Reported are the phenotypic mean and standard deviation (SD), and the posterior mode and 95% credible intervals for the proportion of variation (H2) that was explained by Daphnia F2-genotype. H2 is equivalent to broad-sense heritability.
