Sentences with phrase «allelic frequency»
The phrase "allelic frequency" refers to how often different versions of a gene, called alleles, appear in a population. It tells us how common or rare a particular allele is among individuals in a group. Full definition
The different FY allelic frequencies in individuals from North compared to Southeastern Brazil, may be due to the contribution of the three major ethnic groups (Europeans, in particular Portuguese; Blacks and Amerindians) in the formation of both populations.

To further determine the specificity of the mediating role of collectivistic cultural values on the association between allelic frequency of the 5 - HTTLPR and mental health disorders, we also conducted regression of mediation on 5 - HTTLPR, individualism — collectivism and two mental health disorders included in the 2008 WHO Mental Health Survey, but not previously associated with the 5 - HTTLPR, namely substance abuse and impulse control.
These reference standards consist of human genomic DNA fragmented to 160 base pairs, representative of plasma - derived cfDNA, and are provided as a set of precisely defined allelic frequencies from as low as 0.1 %.
However, the results in GSDs may not be generalizable to other breeds, since allelic frequencies vary markedly among breeds.
Mitogenomes can recover patterns at greater time depths than microsatellites, which are likely to reflect recent and dramatic changes in nuclear allelic frequencies caused by genetic drift [14,17].
(b) In the mediation regression where both S allelic frequency and cultural value of individualism — collectivism were included as predictors of global depression prevalence across 12 nations, individualism — collectivism remained a reliable predictor (β = − 0.21, p < 0.05), and the effect of S allele frequency decreased significantly (from r (12) = − 0.51 to r (12) = − 0.03; Sobel test Z = − 1.92, p < 0.05).
Allelic frequency is shown alongside each product (%)
Allelic Frequencies and Patterns of Single - nucleotide Polymorphisms in Candidate Genes for Asthma and Atopy in Iceland.
Given that ovulatory dysfunction is a key feature of PCOS, one group investigated a cohort of PCOS patients to determine if there was an association with this polymorphism.68 They reported significant differences in the genotype distribution and allelic frequencies between controls and PCOS patients that supported a correlation with the G / A polymorphism.68 To date, the underlying mechanism has not been established.
Importantly, in the current study, divergent validity analyses indicated that cultural values and allelic frequency of the serotonin transporter gene predicted global prevalence of anxiety and mood disorders, but not impulse control and substance abuse.
