Sentences with phrase «allele frequency differences»

Note that the loci represented are biased towards loci previously ascertained to show sharp allele frequency differences between both ends of the subspecies distributions, and even for some of these we are able to detect introgressed alleles.

To identify signatures of geographically restricted natural selection, the authors searched for DNase I peaks containing variants with significant allele frequency differences between individuals of African, European, and Asian ancestry.

Among individuals with two divergent mitochondrial haplotypes (mt - haplotypes), the genome - wide analyses revealed significant differences in nuclear allele frequencies.

We did not find significant differences or deviations in a consistent direction in the frequency of derived alleles in islands of divergence within O. c. cuniculus or in either subspecies when defining differentiation based on the proportion of fixed differences versus shared polymorphisms (Figure 3); however, intervals of high FST in O. c. algirus did show a significant skew towards high frequency derived alleles.

The differences between the samples are highest in low - frequency alleles and decrease with increasing allele frequency.

Recent studies emphasize that adiposity, like stature, is a polygenic trait, and that population genetic variability primarily comprises different frequencies of particular alleles, rather than major systematic differences [14, 60].

This approach is most effective if many breeds are used or if mixed breed animals are used in addition to purebreds to reduce the false positives due to breed differences in allele frequencies.

There were no differences in 5 - HTTLPR allele frequency between the two groups (χ2 = 0.37, df = 2, and P = 0.83).
