A) Schematic representation of the chain-crossing scheme used to produce the RIX panel: Each RIL was crossed with its adjacent RIL. Exceptions to this scheme occurred due to differences in flowering times. B) Kinship represented as heatmap of pairwise similarities between the 214 RIX genomes reconstructed starting from MAGIC maize RILs: white and red represent low and high similarities, respectively. On the left and top side, a hierarchical tree represents relationship between RIX. Samples were ordered according to R base function hclust(). The histogram in inset represents the count of occurrences (i.e. similarity, y axis) vs the similarity value subdivided by 1,000 bins
