Partial DNA profile
Definition
A DNA profile in which results were obtained at fewer loci than the full STR panel used. Partial profiles arise from degraded DNA where short DNA fragments remain but longer amplification targets have been lost. They may support probabilistic interpretation but carry greater uncertainty than full profiles.
