Fig. 2From: A survey of functional genomic variation in domesticated chickensAllele frequency distribution for different functional classes of putative deleterious variants. Deleterious variants (deleterious missense and stop-gained) show distinct allele frequency spectra compared to variants considered to be neutral (synonymous, missense tolerated). Missense variants are classified by SIFT (deleterious: SIFT score ≤ 0.05, tolerated: SIFT score > 0.05)Back to article page
