  1. Overall Spearman‘s correlation (r correlation coefficients and P value) between all the initial parameters (initial BW, week’s old and gender) of CC lines and recorded traits (ST: n = 92, CBW1: n = 92) to determine potential influence (A). Two-way ANOVA’s comparison across eight selected CC lines and A/J commercial inbred line to evaluate gender influence on recorded traits (MST and CWB1) (B)
