"WebJun 17, 2024 · About mapping quality. Mapping qualities are a measure of how likely a given sequence alignment to its reported location is correct. If a read's mapping quality is low (especially if it is zero, or mapQ 0 for short) the read maps to multiple locations on the genome (they are multi-hit or multi-mapping reads), and we can't be sure whether the … " - Reads mapped to multiple loci
