The paper shows that weakly selected QTLs linked to regions with associative overdominance can increase additive genetic variance, but recessive deleterious alleles may reduce fitness when exposed by selection.

This study uses simulations to show how ecological and genetic factors shape the genetic architecture of local adaptation, highlighting the role of demographic history and allele age in genotype-environmental associations.

The paper investigates the genetic architecture of climate-adaptive traits in Douglas-fir, finding polygenic and redundant patterns that complicate genomic predictions of maladaptation to future climates.

The paper uses pool-seq and exome capture to identify SNPs in two conifer species, showing high correlation between pooled and individual sequencing with improved accuracy using haploid tissue.
