Fig 2. Manhattan plot of loci associated with fertility in a genome-wide association analysis using an efficient mixed-model association eXpedited with a genomic relationship matrix (EMMAX-GRM).
The blue horizontal line represents the Wellcome Trust threshold for moderate association (p < 1 × 10−5) and the red line represents the threshold for loci that are highly associated (p < 5 × 10−7) with fertility. The–log10 p-values are indicated on the Y axis, and the bovine chromosomes are listed on the X axis.
