From: Genome-wide association study reveals the genetic architecture of root hair length in maize
GWAS showing significant P-values associated with root hair length based on the mixed linear model (MLM). a Manhattan plots of MLM for root hair length. The horizontal dashed line represents the significance threshold -log10(P) = 5.2. b QQ plot of MLM showing the ratio of the observed and the expected P-values for root hair length. The solid diagonal lines represent agreement between observed and expected probability distributions assuming null SNP–trait association
