Sentence examples for acted on a mutation from inspiring English sources
If one of the populations was recently separated from the other and selection acted on a mutation that arose in an ancestral population, the partial selective sweep is an approximation of the true process with the assumption that most of the neutral variation appeared before the introduction of the selected mutation.
When selection acts on a mutation, it also affects linked sites and leaves a signature in the flanking chromosomal regions.
The researchers found an average of around 60 genetic changes per tumor, but they also discovered that most of those mutations acted on a core set of just 12 cellular pathways.
However, recent studies [9], [14] have detected significant positive selection on wx in Chinese waxy maize, suggesting that strong improvement might have acted on the mutation genotype to maintain the glutinous phenotype.
The patterns of fixation will vary depending on whether selection has acted on new mutations (leading to so called hard sweeps) or standing genetic variation (leading to so-called soft sweeps).
Whether the later mutations act on a single pathway or multiple, different pathways will require the detailed dissection of the oscillator's mechanism.
The N279K mutation might act on a proposed purine-rich exonic splice enhancer that reduces the relative expression of some 3R tau isoforms (D'Souza et al., 1999).
In the classical selective sweep model, positive selection acts on a new allele that arises by mutation, driving it to fixation within a population or species (Maynard Smith and Haigh 1974).
When a reversal acts on a segment that contains this gene, we replace that mutation with a reversal of the other part of the genome instead.
One of the essential problems in population genetics is determining how natural selection acts on the mutation rate of an organism during long-term evolution.
Second, it is possible that selection acted on standing genetic variation caused by old mutations, meaning that a casual polymorphism is not necessarily associated with any particular haplotype.
