The theoretical covariance between pairs of markers is calculated
from either paternal haplotypes and maternal linkage disequilibrium (LD) or
vise versa. A genetic map is required. Grouping of markers is based on the
correlation matrix and a representative marker is suggested for each group.
Employing the correlation matrix, optimal sample size can be derived for
association studies based on a SNP-BLUP approach.
The implementation relies on paternal half-sib families and biallelic
markers. If maternal half-sib families are used, the roles of sire/dam are
swapped. Multiple families can be considered.
