Evidence claim

bStatistic: description

Description of bStatistic

The background-selection B value: the expected fraction of neutral diversity remaining at a site, computed from the local recombination rate and the density of conserved segments.

Replace a category-only description with a sourced functional description (issue #88). Historical releases retain the original value.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Evidence table

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
