What this means
claude:haiku

Short-read WGS of Drosophila melanogaster from an Illumina Genome Analyzer II with 26× coverage and substantially improved quality (78% Q20 bases, 66.5% Q30), offering a reliable foundation for SNP discovery and polymorphism mapping in this model organism. The measured metrics and good coverage depth make this sample suitable for population-level whole-genome sequencing studies and variant annotation.

How this grade was computed
Weighted mean of 4 scored metric(s) → 61/100

The D grade is a transparent weighted average. Each metric below scored from 0–100% against the published WGS thresholds, weighted by its importance; nothing is hidden or subjective.
