The parasite population's reproductive structure was estimated through the association index (IA), and the degree of genetic differentiation and variation was determined using AMOVA.

Nonetheless, it is worth considering how the frequency of localized extinctions might act on geographic differentiation, or variation among spatially defined groups.
Here we investigate patterns of genetic differentiation, genetic variation, and bottlenecking using nine variable microsatellite loci.
We integrated 1857 diverse maize accessions from America, Africa, Europe and Asia to investigatetheir genetic differentiation, genomic variation using 43,252 high-quality single-nucleotide polymorphisms SNPs),combing GWAS and linkage analysis strategy to exploring the function of relevant genetic segments.
Hybrid swarms common in natural zones of contacts between different taxa lead to the great genetic and ecological differentiation and variation of the polyploid taxa in the A. millefolium species complex.
The variability in gene methylation level has various sources, including tissue differentiation, individual sample variation, and technical variance.
However, we did not find evidence that genetic differentiation and morphological variation among lakes were associated; suggesting that shape variation in roach did not have a heritable component detectable in our analysis.
The precision of the calibration model was also estimated at various concentration levels, to facilitate the differentiation between the variation in drug concentration due to the analytical method's measurement uncertainty and the variation in the drug distribution throughout the powder blend.
This would be especially expected in narrow-endemic species, whose ecological niche is often so restricted that indeed homogeneous selective forces are likely to occur, whereas small population sizes and restricted dispersal are likely to produce strong differentiation for neutral variation.
