Title

Mapping Quantitative Trait Loci in Multiple Populations of Arabidopsis thaliana Identifies Natural Allelic Variation for Trichome Density

V Vaughan Symonds; A Veronica Godoy; Teresa Alconada; et al. Genetics 2005. doi:10.1534/genetics.104.031948

Other claims from this paper (5)

Observation Seven of nine trichome-density QTL were population-specific.
Observation Two trichome-density QTL mapped in all four populations.
Observation Lineage-specific alleles that increase trichome density persist in natural populations.
Observation Most genetic variation in trichome density was additive.
Recommendation The authors conclude multiple populations help characterize the genetic architecture of natural variation.
