The phrase "a given trait in" is correct and usable in written English.
It can be used when discussing a specific characteristic or quality that is present in a particular context or subject.
Example: "Researchers have identified a given trait in the species that contributes to its survival in harsh environments."
Alternatives: "a specific characteristic in" or "a particular feature in".
For a given trait in a particular population, marker density may be a key factor.
I have proposed that a given trait in different species may be underlain by different size networks and that these differences can drive evolutionary ecological patterns such as competitive dynamics.
Variables studied in this work are summarised in Table 1. a Presence/Absence (indicated by +/-) of a given trait in grape berry tissues.
For a given trait in a particular population, increasing the marker density can increase the resolution of the genetic map, thus enhancing the precision of QTL mapping [ 17].
To calculate this index (CFA2 in Leung et al. [ 32]), individual FA value was divided by the average FA of a given trait in the population of interest so that all traits contribute equally to CFA measure.
The SNP effect estimates for a given trait in the population of BB cows were compared with those for the same trait in the population of TC cows to select SNPs that had large effects in both populations and in either the same or opposite directions.
If in a particular treatment, the QTL for a given trait appeared in the same genomic region in more than one year, the QTL was considered as stable QTL [ 14].
A recent study defined a probabilistic trait locus (PTL) as "a locus that changes the probability that an individual expresses a given trait value in a given genomic and environmental context" and expression PTL as a locus affecting the expression variability of a given gene (Fehrmann et al. 2013).
In principle, an increase in marker density should result in higher LD between the markers and the quantitative trait loci underlying a given trait, and consequently in more accurate genomic predictions.
The amount of genetic variation for a given trait can vary in space and time owing to genotype-by-environment interactions (Pigliucci 2001) or the erosion of genetic variation by natural selection.
If the variance ratio is fixed for all analyses of a given trait, then the change in accuracy is due to the change in the inverse of the coefficient matrix.
