There are two objects in the loaded data file:
genotypes: An object of class
"snp.matrix" containing the SNP
genotype data for both parents and affected offspring
pedData: A data frame containing the standard six fields
for a LINKAGE pedfile. The are named familyid,
member, father, mother sex, and

The two objects are linked by common row names.
Coding in the pedData frame is as in the LINKAGE package,
except that missing data are coded NA rather than zero
