Bloom 2015 approach to mapping

Approach as I understand it:

1) Generate 6 kinship matrices built using all but one excluded chromosome (e.g. mapK_I = CHROM II, III, IV, V, X)
2) Calculate BLUPs using each kinship matrix
3) Subtract BLUPs from phenotype 
4) Map by simple correlation 

For mapK_I:
cor(Y - Y.BLUP ~ marker)$p.value
For all markers on chromosome I
