Table 3 Effects of family, sex and plumage colour genotype (B/B, B/+, and +/+) on gross body composition (mean ± SD) of 24-week old Japanese quail, and comparisons between genotypes

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

  1. 1:Carcass weight was used as a covariable for the analyses of abdominal adipose tissue, pectoralis muscle weight, liver weight, and heart weight.
  2. 2:Total weight of the right pectoralis major and pectoralis minor muscles.
