Phenotypic variation in mammals is frequently attributed to the action of quantitative trait loci (QTL) or the environment, but may also be epigenetic in origin. Here we consider a mechanism for ...

Genetic variation among human races can be observed ... The researchers therefore concluded that the changes responsible for human phenotypic diversity have come about through both positive ...

With the support of the Bill & Melinda Gates Foundation, we are developing genetic and genomic resources that can be used to leverage the phenotypic variation in sorghum. By developing tools in the ...

As a population geneticists, our major goal is to understand what evolutionary mechanisms lead to genetic and phenotypic variation that we observe in these different scales. We work on forest tree ...
