He recently coordinated a project that allowed his company to develop plants with homogeneous genetic traits that will produce predictable phenotypes when crossbred with other plants.
Within the national conservative framework, an ethnic group sharing homogeneous, "German" traits living together as a nation-state is the most desirable.
As this family exhibits a great diversity in shell morphology but extremely homogeneous anatomical traits, the systematics of Lymnaeidae has long been controversial.
However, we could not establish whether the observed differences in expression were due to varying enrichment of a specific sub-population or to homogeneous, donor specific, traits.
Tests for differentiation among groups require that there is a homogeneous distribution of traits within groups.
Within a single cluster, the subjects are relatively homogeneous, sharing similar traits and being dissimilar to subjects in other clusters.
Because the literature has largely shown that people affected by unipolar major depression and anxiety disorders present homogeneous patterns of personality traits compared to other subjects [ 25- 28, 33- 36], the 55 participants with depression and/or anxiety lifetime diagnosis were regrouped.
This theoretical background has been used to identify traits undergoing homogeneous or heterogeneous selection, for which the amount of genetic differentiation would be smaller or larger, respectively, compared to that observed for likely neutral loci (Bonnin et al. 1996; McKay and Latta 2002; Le Corre and Kremer 2003).
Regardless of the trait for which heterogeneity is assumed, genetic heterogeneity has been defined in most models by a small number of homogeneous subgroups with different trait values.
Furthermore, it is to be expected that if a trait has high adaptive value (e.g. it enhances foraging efficiency), it should spread and replace less efficient variants until the trait is homogeneous within the population.
