Fig. 1.

Genetic structure of individual panels. A Folded size frequency spectrums of the eight panels show the panel-wise distribution of minor allele counts (MAC). B Panel-wise LD decay plots. Y-axis displays the average squared correlation coefficient (R²) between markers when sorted after the average distance and binned into groups of 1000 or 5000 seven-parent-MAGIC and four-way-cross). For each bin, the x-axis displays the average distance in Mbp between two SNPs. The green line is the fitted loess curve with half its maximum R² indicated by the dashed line
