Why it matters in GWAS

Ignoring relatedness inflates association statistics and biases heritability-related summaries; modeling or pruning related samples is standard. See also sample structure (ancestry, admixture) which often interacts with relatedness.

Example usage

"The methods section includes Relatedness to support interpretation of the primary findings."

Related-term network

Click any node to open that term page.

Node order. The current term is first. Next come every page linked from Related terms, in the same top-to-bottom order as that list. Then new terms appear in two-hop layers: for each of those direct neighbors (in that same order), their related terms are appended if not already listed. A third pass does the same for two-hop nodes. The walk stops when a fixed maximum number of nodes is reached.
