Sentence examples for to the fixation of a from inspiring English sources

Genetic drift can lead to the fixation of a particular allelic variant in a population without any selective pressure.

Of course, being dog-sensitive and being dog-look-alike-sensitive are connected, but the problem here is that both being dog-look-alike-sensitive and being dog-sensitive can increase fitness in ways that lead to the fixation of a genotype.

Each simulation consisted of a series of steps, each corresponding to the fixation of a mutant allele, and thus the inversion of one bit of the genotype.

We found that, in addition to the fixation of a standing beneficial mutation associated with a large phenotypic effect, a constant input of genetic variance by new mutations has likely contributed to a linear response to selection over generations.

In addition to the fixation of a standing beneficial mutation associated with a large phenotypic effect, a constant input of genetic variance by new mutations has likely contributed to the response.

Recombination may have reduced genetic and phenotypic differentiation among the core genotypes, while clonal evolution in the separate lineages may have led to the fixation of a large number of genetic differences.

In contrast, strong linkage disequilibrium in early generation hybrids in combination with strong selection would effectively lead to the fixation of an entire block of a chromosome, dragging along alleles controlling other traits within that genomic region.

However, there are several potential issues, including biomechanical changes from the anterior-posterior fusion, surgical risks and complications, increased cost of the surgery, and increased operative time due to the fixation of an additional PSF [ 1, 22].

The air tube tip of the instrument was rebuilt to allow the fixation of a mirror.

Similarly, genetic diversity within islands was greater for nuclear genes relative to plastid genes, and the elapse time between the formation of two consecutive Hawaiian islands is probably too short to allow for the fixation of a single allele within each island.

One route to gene loss is the fixation of a defective allele in the population followed by eventual deletion of the now neutrally evolving segment of DNA.
