Table 1. Phenotypic descriptive statistics and genetic analysis of the oviduct.

Trait	No. of samples	Mean ± SD	CV (%)	CI (%)	Correlation (p/g)	h2snp
OL (cm)	1,469	48.18±6.70	13.91	13.40–14.43	0.614	0.354(0.044)
OW (g)		41.46±9.69	23.37	22.50–24.49	0.799(0.051)	0.392(0.043)

Abbreviations: Mean = arithmetic mean; SD = standard deviation; CV = coefficient of variance; CI = confidence interval of the CV; Correlation (p/g) = the p-phenotypic correlation, g-genetic correlation; h²_snp = SNP-based (h²_snp) heritability. OL = oviduct length; OW = oviduct weight.
