Table 1 Parameters (mean ± SD) and coefficients of determination of the growth curves1 for "white" homozygous (B/B), "silver" heterozygous (B/+) and "wild-type" recessive homozygous (+/+) Japanese quail, effects of the family, sex, and genotype on the parameters of individual curves, and comparisons between plumage colour genotypes

From: The "silver" Japanese quail and the MITF gene: causal mutation, associated traits and homology with the "blue" chicken plumage

  1. 1: Obtained with the monomolecular model: body weight = A-Bw exp(-kt), where A is the asymptotic body weight (g), Bw is the range of body weight from hatching to asymptotic weight, k is the relative rate of growth, and t is the age in days.
  2. 2: CD = coefficient of determination.
  3. *:p < 0.05; **:p < 0.01; ***:p < 0.001; NS: not significant.
