Loci Tracing in Populations
In order to visualise the distribution of traits associated with height loci were traced amongst provenances. Loci associated with tree height from the CANCOR analysis were selected and were searched for in the 80 geographic provenances using VCFtools v0.1.16. Each locus was labelled with a positive and negative effect on height based on the CANCOR analysis. Mean number of loci per provenance associated with a negative or positive change in height were counted using R dplyr. Number of positive or negative loci per provenance were geographically mapped using the R package naturalearth (South, 2022).
