Morphology
The meaning 'a unique identification pattern derived from DNA' follows directly from combining 'genetic' (relating to genes) with 'fingerprint' (a unique identifying pattern). This is a transparent, literal/metaphorical extension where the idea of a fingerprint is applied to genetic material—an easily inferable concept common across languages—so learners who know both constituents should understand it.
Etymology
Genetic fingerprint uses the image of a fingerprint to describe a person's DNA. Just as a fingerprint is a unique mark on the skin, DNA makes a unique pattern inside a person, so the phrase means a special pattern used to 'identify' someone.
