The phrase "a locus that has" is correct and usable in written English.
It can be used in contexts related to mathematics, biology, or any field where a specific location or point of interest is being described.
Example: "In geometry, a locus that has certain properties can help define the shape of a figure."
Alternatives: "a point that possesses" or "a location that contains".
In this example, the recombination signal is positioned within a locus that has been disrupted by homologous recombination.
If the DSB arises at a locus that has been replicated, a template is available in the form of a sister chromatid.
H3K4me2 occupancy can be used as a tracer to mark a locus that has undergone DNA demethylation.
Large differences in allele frequencies between populations may signal a locus that has undergone positive selection in one geographical area.
However, linkage analysis may not be able to detect a locus that has a small effect [ 4].
Five SNPs were located on chromosome 10q22 q23, a locus that has been reported for migraine several times.
To determine if the Cappb1 gene was equivalent to a locus that had previously been mapped thereby identifying a possible association with an existing mutant, the Jackson Laboratory Mouse Genome Database (MGD) and the Mouse Chromosome Committee Report (1999) were scanned for loci that lie within 10 cM of the map positions of Cappb1.
We then further examined the individual miRNA loci on these four class-associated chromosomes (Table S7) to identify any locus that had a cluster of more than five miRNAs belonging to the same class.
They also carry a mutation in tcaR [16], a regulatory locus that has also been implicated in biofilm formation [30].
This appears to be a novel locus that has not previously been sequenced in birds and it is unknown whether it is expressed and/or polymorphic.
The only replicated locus is APOE, which is a mortality locus that has previously been reported to be the major locus responsible for Alzheimer's disease (Harold et al., 2009; Lambert et al., 2009; Seshadri et al., 2010), a well-known age-related disease.
