The phrase "adjust the marker" is correct and usable in written English.
You can use it when referring to changing the position or settings of a marker, such as in a physical or digital context.
Example: "To improve accuracy, please adjust the marker to the correct position before starting the experiment."
Alternatives: "modify the marker" or "change the marker."
Therefore, it is necessary to adjust the marker-based relationship matrix to the pedigree-based relationship matrix.
The scaling parameter s A is unspecified here since we adjust the marker-based partial relationship matrix to make it compatible with the pedigree-based partial relationship matrices, similar to Christensen et al. [ 17] (see below).
Studies on how to adjust the marker-based relationship matrix to be compatible with the submatrix of the pedigree-based relationship matrix for genotyped animals have been reported [ 4- 6].
Finally, this method performed at least as well as a method based on adjusting the marker-based relationship matrix.
For example, when the population consists of a mixture of breeds, it may be simpler to extend the approach in this paper and specify a parametric structure on the relationships of the animals in the base population and estimate those parameters, instead of developing an appropriate way of adjusting the marker-based relationship matrix of the genotyped animals across breeds.
Furthermore, it has been demonstrated that the accuracy of prediction is improved and bias is reduced by adjusting the marker-based relationship matrix as G(m o ) β + α where α and β are based on the elements in G(m o ) and A11; further details are given below.
In [ 16], first, an average of position specific identical by descent matrices based on linkage information [ 17] (hereafter denoted G FG ) were used instead of the combined relationship matrix (1), and second, the final method consisted of replacing the pedigree-based relationship matrix A by the matrix G FG in matrix (1) and then adjusting the marker-based relationship matrix to the G FG matrix.
Here, we show how to adjust the breed specific marker-based partial relationship matrix, G (A ), to the breed specific pedigree-based partial relationship matrix for the subset of genotyped animals, A 11 (A ), similar to Christensen et al [ 17].
To adjust the deviations of the markers positions, two steps of calibration must be carried out: scaled (see Fig. 2a) and coordinate transformations (see Fig. 2c).
