The phrase "at a selected locus" is correct and usable in written English.
It can be used in contexts such as scientific research, biology, or any field where specific locations or points of interest are being discussed.
Example: "The experiment was conducted at a selected locus to observe the genetic variations in the population."
Alternatives: "at a chosen location" or "at a designated point".
Co-evolution in a pathogen-plant interaction is characterized by the development of resistance in the host and virulence in the pathogen, with natural selection affecting the type of genetic polymorphism found at a selected locus.
We demonstrated analytically that (a) the infection polymorphism between populations is stabilized by local adaptation, (b) gene flow between the populations is reduced but divergence at a selected locus enhanced, and (c) unidirectional CI selects for premating isolation in a mostly uninfected island population receiving migration from a Wolbachia-infected mainland.
Bidirectional CI is therefore a force that increased genetic divergence at a selected locus.
We created the PDG-ACE algorithm to overcome this limitation by mining Entrez Gene text to identify biomedical keywords that are common and significantly over-represented in the descriptions of genes at a selected locus pair, relative to all locus pairs in the genome.
Our analysis shows that (a) the infection polymorphism is stable below a critical migration rate, (b) an (initially) uninfected "island" can better maintain divergence at a selected locus (e.g. can adapt locally) in the presence of CI, and (c) unidirectional CI selects for premating isolation in (initially) uninfected island populations if they receive migration from a Wolbachia-infected mainland.
In some cases, recombination seems to occur at a rate sufficient to uncouple a selected locus from the rest of the genome [ 19].
In genetic algorithms the operation of mutation is usually implemented as a change to a gene at a randomly selected locus in a chromosome.
Here, generalizing the coalescent-based version of the serial founder model as formulated by DeGiorgio et al. (2009), we provide an analytical distribution of the coalescence time for a pair of lineages at a randomly selected locus, along with corresponding expected coalescence times, expected homozygosity values, and FST values.
At the selected locus, allele B has a selective advantage s over the alternative allele b.
Direct evidence includes a demonstration of heterozygote advantage at the selected locus or the absence of a genotype that has maximum fitness in all environments and/or genetic backgrounds.
Figure 3 shows that the former scenario results in higher genetic divergence between the populations at the selected locus over a broad range of migration rates.
