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

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

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)

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.
