The genetic architecture of complex traits in teosinte (Zea mays ssp. parviglumis): new evidence from association mapping.

abstract：:The mutation process at microsatellite loci typically occurs at high rates and with stepwise changes in allele sizes, features that may introduce bias when using classical measures of population differentiation based on allele identity (e.g., F(ST), Nei's Ds genetic distance). Allele size-based measures of differentia...
