 Including haplotypic effects is quite complicated because, for each record //y//<sub>i</sub> we have two copies of the haplotype (i.e. it is like having two herd effects). However they are logically the same. Most programs are not prepared to having two columns in the data file referring to the same, cross-classified effect. Including haplotypic effects is quite complicated because, for each record //y//<sub>i</sub> we have two copies of the haplotype (i.e. it is like having two herd effects).

 The first column is //y//, the second //µ//, 3rd-5th is the number of copies of the haplotype of interest, the 6th column is the effect //t// with 5 levels. The “1 2 3” indicate which is the haplotype associated to the number of copies in 3rd-5th columns. Note, for instance, that the 5th record has 2 copies of the third haplotype. The par file is thus: The first column is //y//, the second //µ//, 3rd-5th is the number of copies of the haplotype of interest, the 6th column is the effect //t// with 5 levels.
