The pedigree represents that portion of the mated pair not seen in the phenotype of the individuals to be bred. Knowledge of the both the phenotype and genotype of the breeding pair is represented by the pedigree. It is influenced by the breed type, conformation and temperament of all the individuals that make up the pedigree, and sometimes dependent upon the repeated influence of an individual (or individuals) appearing within that pedigree as well as where he, she or they occur within it. Each mate contributes 50% of their DNA to the breeding and the 100% is reassembled in the get, but each littermate is an individual with differing genetic makeup depending upon which portions of the parent’s available progenitor genes are combined in that specific progeny.
