Population genetics: A new apportionment of human diversity
A worldwide survey of polymorphic molecular markers shows that the human population is genetically homogeneous, in close agreement with evidence from quite different genes and traits.
متن کاملThe Apportionment of Human Diversity
It has always been obvious that organisms vary, even to those pre-Darwinian idealists who saw most individual variation as distorted shadows of an ideal. It has been equally apparent, even to those post-Darwinians for whom variation between individuals is the central fact of evolutionary dynamics, that variation is nodal, that individuals fall in clusters in the space of phenotypic description,...
متن کاملImplications of the apportionment of human genetic diversity for the apportionment of human phenotypic diversity.
Researchers in many fields have considered the meaning of two results about genetic variation for concepts of "race." First, at most genetic loci, apportionments of human genetic diversity find that worldwide populations are genetically similar. Second, when multiple genetic loci are examined, it is possible to distinguish people with ancestry from different geographical regions. These two resu...
متن کاملA General Model of the Relationship between the Apportionment of Human Genetic Diversity and the Apportionment of Human Phenotypic Diversity.
Models that examine genetic differences between populations alongside a genotype-phenotype map can provide insight about phenotypic variation among groups. We generalize a simple model of a completely heritable, additive, selectively neutral quantitative trait to examine the relationship between single-locus genetic differentiation and phenotypic differentiation on quantitative traits. In agree...
متن کاملAn apportionment of human HLA diversity.
In this study, we estimate the amount of human leukocyte antigen (HLA) genetic diversity in the global human population at three levels of population hierarchy: within populations; among populations within continents and among continents on large sets of HLA population data gathered during the last international histocompatibility and immunogenetics workshops and conferences. The results indica...
