From: Substantial SNP-based heritability estimates for working memory performance
Chromosomewise h2SNP estimates for N-back phenotypes and mean reaction time h2SNP estimates per chromosome are plotted on the y axis. The x axis depicts the chromosomal length in Mb. Circle size indicates the number of SNPs used in the analysis after quality control. Color scheme from red to blue reflects the chromosomal ordering from chromosome 1 to 22, with the X-chromosome colored in black. The black line depicts the regression line for chromosomal length and explained variance (regression coefficients (df=21): (a) r=0.53, P-value=0.009, (b) r=0.56, P-value=0.006, (c) r=0.65, P-value=0.0009, (d) r=0.25, P-value=0.3). SNP, single-nucleotide polymorphism.
