Alternatives: "a specific variation" or "a distinct variation".
Needless to say, the idea that there are intrinsic limitations on producing a particular variation of Hershey's Kisses or M&M's is a purely manufactured one.
They then scanned the genomes of patients with common diseases to look for statistical links between having a disease and having a particular variation.
The listeners who got the highest ratings for empathy, it turned out, possess a particular variation of the oxytocin receptor gene known as the GG genotype.
Instead, it looks as if early in the dog's history — about 15,000 years ago — humans captured through breeding a particular variation in the code for a single gene that produced small dogs that retained essential dog behaviors and characteristics.
Nine years ago, researchers at Washington University School of Medicine, in St . Louis reported that families with a particular variation in the PCSK9 gene had very low levels of L.D.L. ("bad") cholesterol.

Having read the article, a user may be interested in finding out more about a particular structural variation, such as the size of the genomic region that a particular structural variation spans.
The effects of each variant on the rates of several different reactions are determined experimentally, and the results are plotted on graphs; the values resulting from a particular molecular variation in one reaction are measured along one axis and those of the same variation in the other reaction along the other axis.
Only a small percentage of people with autism or schizophrenia will carry a particular genetic variation.
That means that if a test purports to detect a particular genetic variation, it does so reliably.
