An example of a regression tree generated by Gradient Boosted Machine algorithm based on the run of homozygosity of at least 4 Mb status of a SNP (i.e. 0 or 1). The split point for a particular SNP (i.e. A, B, C, D or E) and the subsample bin an observation falls into based on the genotype value is outlined below each circle. Two SNP that are within the same branch of a tree, such as A-B, A-D, B-D, A-C, A-E and C-E, are referred to as descendent pairs and may indicate epistatic effects and would be tagged as an interaction. The SNP that are not within the same branch of a tree, such as SNP pairs B-C, B-E, D-C and D-E, are referred to as non-descendent pairs and may indicate independent additive genetic effects and not tagged as an interaction
