Lactase is encoded by a single genetic locus on chromosome 2.
See also the definition of a genetic locus.
Each origin is at distinct genetic locus and must fire only once per cell cycle.
Most proteins that make up the archaellum are encoded within one genetic locus.
The genetic locus for this gene is Xq26.
Therefore, a single genetic locus is not responsible for the condition.
As discussed above, "zygosity" can be used in the context of a specific genetic locus (example).
The genetic locus for this effect was dubbed Lps.
Each of these hypothetical products was considered a potential allele for the specific genetic locus.
A single genetic locus, however, critical in early eye movement control pathways on chromosome 13q31-q33 has been discovered.
