Three methods of estimating the number of S-alleles in a population have been proposed in the literature (Bateman, 1947; Whitehouse, 1949; Paxman, 1963). These methods, all of which assume that genotype frequencies in the population are equal, are described briefly and are used to estimate ...
The greater the size of the population, the lesser the variability of the frequency of alleles. This is because random changes in allele frequency has...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our e...
Consider a population that does not change in size. If it is assumed that there are an infinite number of possible neutral alleles at a locus and u is the probability that a particular gene mutates to some other gene in one generation, the effective number of alleles n e is computed to...
fumigatus is characterized by signature mechanisms involving expression-upregulating tandem repeats (TRs) in the promoter region of cyp51A accompanied by point mutations within this gene, which decrease the affinity of azoles for the target protein; the most commonly occurring alleles are known as TR...
Answer to: Fill in the blank. The (blank) of a population, resulting from some population crash, will cause the entire loss of some alleles due...
The territorial fishing zones of Australia and Indonesia are contiguous to the north of Australia in the Timor and Arafura Seas and in the Indian Ocean to the north of Christmas Island. The area surrounding the shared boundary consists of a variety of bio-diverse marine habitats including shallow...
(--mind 0.1), and the frequency of minor alleles was at least 5% (--maf 0.05). Only SNPs located on 28 autosomes (GGA1 to GGA28) were considered for the further analysis. After filtering, the genotype dataset to search for and analyse signatures of selection included 44,339 autosomal ...
pollinator populations, leading to decreased inter-population communication and hindering the preservation of genetic diversity within species [8]. Moreover, prolonged intra-population gene flow due to human interference can lead to the accumulation of detrimental alleles [9,10]. Under rapid climate ...
genetic cline that reflects a distinct genetic history. Finally, a comparison between ancient and present-day highlanders confirms ongoing positive selection of high altitude adaptive alleles. Ancient genomes from the Himalayas Fig. 1: Geographic locations for ancient groups and present-day Tibeto-Burman...
gene flow as low as one effective migrant per generation may counteract genetic drift and reduce the frequency of deleterious variation9,10,11, but might also reduce metapopulation genetic variation12, or introduce strongly deleterious alleles13. Therefore, uncovering population history and determining ho...
