CNVs overlapping with PLA2G2D gene region. (A) Log₂ ratio plot of the PLA2G2D gene region. Each point shows the log₂ ratio of the number of Holstein reads mapped to the number of Black Angus reads mapped. Points are coloured based on the log₁₀ p-value calculated by the CNV-seq software. (B) The PLA2G2D gene region as visualized using the UCSC Genome Browser. The precise boundaries of the five CNVs reported by CNV-seq that reside in this region are shown and labelled. The third CNV from the left (Chr2_CNV_29) was tested and validated by qPCR.
