Fig. 1From: Genome-wide association and selective sweep analyses reveal genetic loci for FCR of egg production traits in ducksManhattan and Q–Q plots of the genome-wide association studies for the six egg production traits analyzed. Each dot in the Manhattan plot represents an SNP in the dataset. The black dotted lines indicate the Bonferroni corrected significance threshold (− log10 P = 8.16). The Manhattan plots indicate the − log10 (P) values for genome-wide SNPs (y-axis) against their corresponding position on each chromosome (x-axis), while the Q–Q plots show the expected − log10 (P) vs. the observed − log10 (P). HP, hip-width; FI, feed intake (37 days); EW, egg weight (37 days); FCR, feed conversion ratio (37 days); DFI, daily feed intake; EP, egg production (between 226 and 329 days of age)Back to article page
