Genetic signal similarity across 4 superpopulations. A Overlapping loci across four superpopulations. Shows shared and specific loci in the studied populations for hematological traits, B Illustration of the comparison of multi-trait signals across ancestries. For shared loci a correlation between the vectors of the genetic signal is computed. The squared Pearson correlation gives an indication of how much the multi-trait signal is conserved. C Histogram of multi-trait genetic signal similarity (R2 Pearson correlation) for pairs of lead SNPs located in a shared region. Each panel corresponds to one ancestry pair
