Use selective-breeding and genetics claims carefully
You are selecting a line or evaluating a genetic or breed-true claim.
Use the whole card. The action stays attached to what must be observed and recorded, plus the nearest inference or action the current guidance cannot support.
Observe first
Separate phenotype, pedigree, controlled cross, family structure, marker, candidate gene, population and validation cohort.
First action
Define the trait and scoring method, preserve source-separated families and test offspring across complete generations.
Record next
Record parent identity, cross direction, family, environment, scorer method, every offspring class, missing calls and exclusions.
Stop boundary
Do not turn expression, association, one marker or line name into a causal genotype, purity certificate or guaranteed inheritance pattern.
