A small fraction of the source signal can be diverted to an interferometer and a series of frequency markers generated and placed on the recording of the spectral absorption lines.
In particular, we document in the empirical data that the long-known complicating effects of allele frequency, marker density, and sample size largely reconcile all large-scale surveys.
To identify individual CNVs, we incorporated multiple factors including log R ratio, B allele frequency, marker distance, and population frequency of the B allele using PennCNV [25], [27].
It is difficult to detect statistical associations between diseases and low frequency marker alleles, suggesting that the high odds ratios observed for SNPs with a minor allele frequency ≤ 0.2 were indicative of a "winner's curse".
Our result suggested that designing a low-density chip by selecting low frequency markers with large SNP effects sizes should be helpful for commercial application in Chinese Simmental cattle.
It should be noted, however, that high frequency markers are required to detect all rare alleles in a population [ 67].
To estimate more accurately the SNP frequency markers assembled into haplotypes were tested for association with the texture sub-traits.
To identify SSR loci with as high a frequency of polymorphic markers as found in the B73/Mo17 Indel annotation, specific comparisons between mapping population parents would be needed.
When considering the standard deviation calculated for each marker among the 19 repetitions, it is clear that the method can efficiently detect and reliably quantify genetic variants present in the population at a frequency above 5% (Markers VIT1-4).
However, it is likely that some clusters also represent additional regions where chromosomal rearrangements have occurred [ 9] and, furthermore, that some regions contain other characteristics (such as high gene density) that cause a higher frequency of marker discovery.
