Sentences with phrase «of admixture»

Despite apparent fitness costs, our data suggest that hybridization may spread due to relatively high reproductive success of first - generation hybrids and high reproductive success of a few males with high levels of admixture.

There is a certain disproportion here» unlike in the rest of this book where the proportions of the admixture of confession and of pilgrimage are just about right.

For example, when I scrutinize, in the same way that I scrutinized the notion of self - creation, modern physical notions of what goes on when one billiard ball strikes another, and when I try to understand my sense of agency in terms of an admixture of physical causes and random happenings, I find myself just as bewildered — and a little more forlorn.

Investments in cryptocurrencies are highly speculative, which is why only a small amount of admixture in the portfolio is advisable.

Coloured individuals showed varying proportions of admixture with Khoesan, African and European populations as well as populations from the Indian sub-continent.

We demonstrate that, whereas the mean admixture under assortative mating is equivalent to that of a randomly mating population, the variance of admixture generally increases with higher levels of positive assortative mating and decreases with negative assortative mating, analogous to classic theory on assortative mating by single locus genotypes or traits.

The paper, by C.N. Simonti at Vanderbilt University in Nashville, TN, and colleagues was titled, «The phenotypic legacy of admixture between modern humans and Neandertals.»

«But it is wrong to say that this is a potential trait only of the European race, especially because of admixture.

Although the Green et al. analyses are suggestive of admixture, the role of Neandertals in the genetic ancestry of humans outside of Africa was likely relatively minor given that only a few percent of the genomes of present - day people outside of Africa appear to be derived from Neandertals.

To examine the degree of admixture and incomplete lineage sorting, we looked at each gene topology and compared it to the species tree.

However, the high reproductive success of F1 hybrids relative to post-F1 hybrids with similar amounts of admixture suggests that some of the outbreeding depression is intrinsic.

At the same time it will release us from the dull worldview of life being merely the activity of an admixture of carbon and a few other elements; it suggests the exhilarating possibility that life is fundamentally immortal.

The logo doesn't really give anything away as to what we can expect from the crossover other than that it is a crossover and that there will be some sort of admixture of content from both games appearing in the other.

We suspect that non-hybridized populations will continue to be lost if hybrid source populations are not suppressed or eliminated, and that protection of fishes with even low levels of admixture may facilitate continued expansion of hybridization.

With the GPS tool, the investigators were able to take unknown samples, identify the proportions of admixture — meaning, genetic characteristics specific to certain ethnic groups that were combined because of events like migration or invasion — and then calculate the distance to the nearest known population that shares the same admixture signature, in order to identify place of origin.

He added, «Investments in cryptocurrencies are highly speculative, which is why only a small amount of admixture in the portfolio is advisable.»

As the variance of admixture has been used to infer the timing of hybridization and sex - biased admixture, we consider the implications of assortative mating for inferring population history and speciation.

The best approach is to get people to talk about their levels of admixture, rather than label them or their diseases by race.»

Proportion of genes that support the minor topologies can estimate the proportion of admixture and incomplete lineage sorting across the genomes (Pollard et al. 2006; see Materials and Method for brief discussion).

The decision to use the 20 per cent threshold continues to be controversial because the potential fitness effects of this amount of admixture are unknown, and the threshold used will influence the decision to list by determining the number of populations classified as part of the native taxon (Haig & Allendorf 2006).

This outbreeding depression suggests that even low levels of admixture may have negative effects on fitness in the wild and that policies protecting hybridized populations may need reconsideration.

The fact that the SNPs used for each of these loci fall on the branch uniting divergent haplogroups, which is consistent with ancient vicariance and reciprocal monophyly being attained in the past before hybridization took place, suggests that high levels of admixture may have eroded any clinal differentiation in HPRT1.
