While genotypic frequencies look at the expression of the genes, allele frequencies look at the number of times a specific allele occurs in a population. To find the allele frequency of B in this example multiply 50 by two as there are two B's in the BB genotype. Then add the people wi...
Microevolution is defined as a change in allele frequencies in a population over generations. Explain what an allele is in genetic terms. Which mechanism of evolution is responsible for the change in allele frequencies over time due ...

Spotted hyenas are an exception in the animal kingdom not only due to female dominance over males, but also because of the strict female linear hierarchy which determines priority of access to resources and produces considerable female reproductive skew.
(Reinhardt et al.2019). Wolf expansion in Germany showed comparable patterns to the recovery in Western Poland with subsequent wolf colonization in a north-easterly direction (Nowak and Mysłajek2016). The haplotype frequencies in our study region are highly similar to that in Western Poland (...
[1]. A SNP that is observed at a higher incidence in cases compared to controls can be shown to be significantly associated with the phenotype, which is dependant on the panel sizes and the measure of the difference in observed allele frequencies between the panels. However, a statistically ...
Plasma ctDNA was isolated for evaluating variant allele frequencies (VAF) of somatic mutations in 47 cancer-related genes using next-generation sequencing (NGS), ctDNA response was defined as clearance of maximum VAF (maxVAF) compared to baseline. CT scans were performed after every two cycles ...
However, it is well known that HLA allele and haplotype frequencies differ significantly between populations. We estimated high-resolution HLA-A, -B, -C, -DRB1 haplotype and allele frequencies of donors within DKMS German Bone Marrow Donor Center with parentage from 17 different countries: Turkey,...
Distribution of allele frequencies at a set of loci. The shape of the distribution can be used to infer demography and natural selection (for example, through hitchhiking). Spurious gene expression Gene expression with no selective advantage. A necessary concept but one that in practice is hard ...
It is doubtful this bias can be fully ascribed to standard ascertainment bias (that is bias for markers which are more polymorphic than average in the sample used for marker discovery). We suspect these loci have been further selected for their high difference in allele frequencies between ...
