The process of admixture reunites datingmentor.org/positive-singles-review/ gene pools from two or more populations, which might have diverged due to genetic drift, mutation, and selection. Admixture, which may occur repeatedly over several generations, followed by recombination, leads to chromosomes that are essentially mosaics of ancestry segments (Fig 5) . In a randomly mating admixed population, ancestry segments segregate randomly with respect to the environment, which decouples the between-population genetic effects on the phenotype from the environmental effects, allowing for the estimation of the genetic variance underlying a phenotype. We propose that a method recently developed to estimate heritability in admixed populations (Zaitlen et al. (2014)) , might provide a valid estimate of c. Zaitlen et al. (2014) extend the method developed by Yang et al. (2010) , using local ancestry at SNPs, instead of genotypes, to construct the genetic relationship matrix among admixed individuals. The proportion of phenotypic variance in an admixed population that can be explained by local ancestry (h_y 2 ) is conceptually equivalent to c between the parental populations. Our reasoning is that, on a genotypic level, the genetic variation in an admixed population should be the sum of the genetic variation within the parental populations and the genetic variation between them. Variation at the scale of local ancestry only represents genetic variation between populations (Fig 5). Thus, the proportion of phenotypic variation that can be explained by local ancestry (h_y 2 ), should be equivalent to c.

Genetic variation between them parental populations is illustrated by the variation during the shade of this new chromosomes, whereas genetic version during the communities is actually portrayed by hue intensity.
