Figure 3.

(a) Manhattan plots of mapped single nucleotide polymorphism (SNP) markers associated with body weight. Each dot corresponds to a SNP within the data set. The dot color represents the chromosome on which the SNP is located; the dot position represents the −log₁₀-transformed p-value of the SNP. The horizontal dotted line denotes the genome-wide significance threshold level (−log₁₀(p) > 5.83); the solid line denotes the suggestive threshold level (−log₁₀(p) > 4.53). (b) Quantile–quantile plot of the genome-wide association study.
