For example, refSNP page for rs222 reports: "MAF/MinorAlleleCount:G=0.249/542". This means that for rs222, minor allele is 'G' and has a frequency of 24.9% in the 1000Genome phase 1 population and that 'G' is observed 542 times in the sample population of 1088 people (or 2176 chr...

What does an allele frequency measure? What is meant by allele frequency? How is a recessive allele different from a dominant allele? What is the relationship between a gene pool and allele frequency? Describe a scenario where the recessive allele frequency would increase. ...
Earlier works on copy number inference4,29,34,47,48 transform integer copy numbers into a discrete set of real-valued latent parameters: read depth ratio (RDR) μ and B allele frequency (BAF) p. We use the same parameter transformation and split the problem into two steps: CalicoST infers...
Explain how to calculate the relative frequency in a gene pool. What is the general rule used? Give an example. Define the coefficient of kinship and explain how it can be used to determine whether someone is a carrier for a genetic disease. ...
allele in one ethnic population might be a minor allele in ethnically different populations. For example, when 313 genes in 82 unrelated individuals of five geographically isolated subgroups were examined, more than one-third of the selected genes had no major allele with a frequency exceeding 50%...
Figure1. Example VCF One of the most used values for filtering variants in a somatic mutation workflow is the Alternate Allele Frequency for each sample. This field is not always provided directly in the VCF data but don’t worry, VarSeq will automatically calculate the frequency using the prov...
Use an example. Why is gene flow important to evolution? How do alleles become more common in genetic drift? What does high gene flow mean? Explain recombination frequency. How is genetic drift like molecular diffusion? How does recombination contribute to offspring diversity? Does gene flow ...
