Exempel på hur man kan använda ALLELIC i en mening

• Genetic drift, also known as random genetic drift, allelic drift or the Wright effect, is the change in the frequency of an existing gene variant (allele) in a population due to random chance.
• If there are more than two different allelic forms, the frequency for each allele is simply the frequency of its homozygote plus half the sum of the frequencies for all the heterozygotes in which it appears.
• Since natural allelic mutations are rare prior to screening geneticists often mutagenize a population of individuals by exposing them to a known mutagen, such as a chemical or radiation, thereby generating a much higher frequency of chromosomal mutations.
• In cases of allelic heterogeneity, the MIM number of the entry is followed by a decimal point and a unique 4-digit number specifying the variant.
• This correlation is influenced by several evolutionary processes, such as genetic drift, founder effect, bottleneck, genetic hitchhiking, meiotic drive, mutation, gene flow, inbreeding, natural selection, or the Wahlund effect, but it was originally designed to measure the amount of allelic fixation owing to genetic drift.
• Weyers acrofacial dysostosis is due to another mutation in the EVC gene and hence is allelic with Ellis–Van Creveld syndrome.
• In the final analysis step of MLST, the relatedness of isolates are made by comparing allelic profiles.
• Gene conversion can be either allelic, meaning that one allele of the same gene replaces another allele, or ectopic, meaning that one paralogous DNA sequence converts another.
• Such electropherograms may be used to determine DNA sequence genotypes, or genotypes that are based on the length of specific DNA fragments or number of short tandem repeats (STR) at a specific locus by comparing the sample to internal size standards and allelic ladder data using the same size standard.
• For instance, the study of an allelic series for Fgf8, an important gene for craniofacial development, with decreasing levels of gene expression demonstrated that the phenotype remains canalised as long as the expression level is above 40% of the wild-type expression.
• KIR receptors can distinguish between MHC I allelic variants, which allows them to detect virally infected cells or transformed cells.
• Other major diseases displaying allelic heterogeneity are allelic mutations in the dystrophin gene which cause Duchenne dystrophy and mutations in the CFTR gene that are known to causes cystic fibrosis.
• 83% of allelic variation within the genome derives from its teosinte ancestors, primarily due to the freedom of Zea species to outcross.
• Infantile systemic hyalinosis is an allelic autosomal-recessive condition characterized by multiple skin nodules, hyaline deposition, gingival hypertrophy, osteolytic bone lesions and joint contractures.
• The loci of the Dark budgerigar mutation and the Blue allelic series are situated on the same autosome, so the Dark mutation is linked to the Blue allelic series (see genetic linkage).
• A best suitable format for optimal allelic and haplotypic HLA frequency estimations, based on the list of allele pairs that account for the genotyping information, has been published.
• It appears to be the mechanism targeting RASEF in uveal melanoma, and allelic imbalance at this locus supports a TSG role for the Ras and Ef-hand domain containing.
• Originally hybrizymes were defined as "unexpected allelic electromorphs associated with hybrid zones", a formal term proposed by renowned conservation geneticist and biogeographer David S.
• The detection limit of CAPP-Seq is affected by three main areas: the input amount of ctDNA molecules, sample cross-contamination, potential allelic bias in the capture reagent, and PCR or sequencing errors.
• Charcot-Marie-Tooth disease-5, Arts syndrome and X-linked nonsyndromic sensorineural deafness present three clinically distinct but genetically allelic disorders, caused by reduced phosphoribosylpyrophosphate synthetase 1 (PRS1) activity due to PRPS1 mutations.
