Total_Leg_Length_T1 phenotype

GWAS results were precomputed for all phenotypes using PLINK2 [v2.00a3LM (1 Jul 2021)] and corrected for the 6 main covariates defined in Huang et al., 2014. These covariates are the same than the ones used in the DGRP2 website.
GWAS results were computed on dm3 genome.

We performed a gene enrichment calculation (Fisher's exact test) of all GWAS-associated genes at p < 0.001. Genesets were taken from two database: the Gene Ontology (GO) and the FlyBase phenotypes. GO enrichment FlyBase phenotype enrichment
