Trait-marker testing can provide useful information about specific inherited variants associated with production or eating-quality traits. Results help breeders plan matings and compare candidates, but they do not describe the entire genome or guarantee a particular carcass.
A genotype is the tested genetic state at a particular marker. Phenotype is the observed result created by many genes plus nutrition, age, sex, health, activity, stress, harvest condition, processing, aging, and cooking.
A favorable marker cannot rescue poor structure, slow development, infertility, excessive fatness, weak muscling, or inconsistent family performance.
Testing adds value because it becomes part of a documented selection system.
Use testing to identify possible strengths, avoid undesirable combinations when evidence supports doing so, and select candidates for further evaluation. Write the expected result before breeding and compare that expectation with the mature litter and pork.

No. A marker may inform probability for a specific trait, while many genes, management, processing, cut, and cooking influence tenderness.
No. Parentage compares identity and biological relationships; trait tests examine selected variants associated with particular characteristics.
No. Selection must protect structure, fertility, temperament, diversity, health, and whole-herd performance.
Testing provides additional inherited information that can improve planning when it is verified and combined with accurate performance records.
