Description Usage Format Details Examples
The first 5 columns give the pedigree id, individual id, father id (0 if founder), mother id (0 if founder), and sex (1=male, 2=female, 0=unknown), in that order. Note that these fields need to be numeric. The 6th column is the affection status (1 = unaffected, 2 = affected). From the 7th column, every consecutive two columns are the alleles at a SNP marker. For males, these two alleles at a SNP marker are the same, because males have only one X chromosome.
