Genetic drift is a change in allele frequencies that occurs by and unlike mutations it tends to eliminate alleles from populations. What five characteristics must a population have to never have a change in allele frequencies? Which of...
The first includes such models as the one studied above, in which specificities leading to incompatibility arise by mutation from an ancestral allele without such specificities. Such a change is hard to imagine, but the reverse change can occur from an active S-allele to one with no pollen ...
Each mammalian autosomal gene is represented by two alleles in diploid cells. To our knowledge, no insights have been made in regard to allele-specific regulatory mechanisms of autosomes. Here we use allele-specific single cell transcriptomic analysis to
Although any base pair change is caused molecularly by mutation, the word mutation is now typically used in a more restricted sense, implying disease-causing mutation. An allele that is frequent (>1%) in the general population is called a polymorphism. With polymorphisms found every few hundred ...
allele changedecentralized selectionsimple sequence repeatsChanges in allele type, allele frequency and genetic diversity because of selection by individual farmers and breeders were assessed using simple sequence repeats (SSRs) during one cycle of selection in a decentralized participatory barley breeding ...
The allele-specific CTCF binding peaks must satisfy "total number of allele reads in the peaks are larger than 10" and "the fold change between alleles is larger than 2". The percentage of the allele-specific CTCF peak was calculated by the number of allele-specific CTCF peaks divided by ...
Significant changes in variant allele frequency is backed by performing a U-test on change in read depths of the focus sample compared to that of the control sample (Fig. 5). The combined assessment of variant allele frequencies and read depth ratios enables the researcher to locate copy-...

BAD calling with Bayesian changepoint identification To construct genome-wide BAD maps from filtered heterozygous SNV calls, we developed a novel algorithm, the BAD caller by Bayesian changepoint identification (BABACHI). At the first stage, BABACHI divides the chromosomes into smaller sub-chromosome...
