What this means
claude:haiku

Whole-genome short-read sequencing of C. elegans on the HiSeq 2500 provides 16.5× coverage with 9.4 million reads at high base quality (97.6% Q20, 91.9% Q30), enabling confident SNP and small-indel discovery across the ~100 Mb genome. The dataset supports variant mapping in forward genetic screens and population genomics studies. Moderate coverage is sufficient for variant calls at typical allele frequencies in this compact model organism.

How this grade was computed
Weighted mean of 4 scored metric(s) → 76/100

The C 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.
