Frequency of Gc Alleles and a Variant Gc Allele in Iceland

Human Heredity, 1980
The gene frequency for Gc1 and Gc2 in an Icelandic population was found to be 0.71 and 0.29, respectively. An electrophoretic variant similar to Gc Norway was detected in 5 individuals of the same family. A pedigree of 14 family members, including two spouses, is presented.

THE TIME REQUIRED FOR ALLELE FREQUENCY CHANGE

The ANZIAM Journal, 2017
In evolutionary theory, a key issue in selection theory is the expected time for a given amount of allele frequency change to occur. Crow and Kimura, by assuming weak selection, presented explicit results for several important cases of the directional selection and of the stochastic process.

Apolipoprotein E allelic frequency in elderly smokers

American Journal of Medical Genetics, 1998
Susceptibility genes for human diseases (e.g., cancer and atherosclerosis) increase disease risk by altering the metabolic activation of exogenous (e.g., carcinogens) and endogenous (e.g., cholesterol) compounds. The function of these genes, and subsequent risk, can be adversely affected by polymorphisms.

ALFRED: An allele frequency database for anthropology

American Journal of Physical Anthropology, 2002
AbstractThe deluge of data from the human genome project (HGP) presents new opportunities for molecular anthropologists to study human variation through the promise of vast numbers of new polymorphisms (e.g., single nucleotide polymorphisms or SNPs). Collecting the resulting data into a single, easily accessible resource will be important to facilitate

Variable allele frequency threshold

2022
The present invention relates to monitoring a patient's response to therapy. In order to improve the monitoring of a patient's response to therapy, a method is provided to set a plurality of allele frequency thresholds to accounting for variations among tumours and patients.

D1S80 allele frequencies in a Chinese population

International Journal of Legal Medicine, 1994
Allele frequencies for the VNTR locus D1S80 were determined in a Chinese population sample using the polymerase chain reaction and subsequent analysis of the amplified products by polyacrylamide gel electrophoresis and silver staining. A total of 18 nominal D1S80 alleles were observed in 105 unrelated Chinese.

Estimating allele frequencies of hypervariable DNA systems

Forensic Science International, 1991
Several polymorphisms of human DNA have been shown to be hypervariable due to the recurrence of a variable number of tandem repeats (VNTRs) in the lengths of allelic restriction fragments. The recurrence of allelic variants in this novel class of polymorphisms seems to comply well with a model of continuous random variables.

Random variation of allele frequencies

1995
In the preceding chapters it was mostly (implicitly) assumed that the populations considered consisted of infinitely large numbers of plants. In this chapter, population genetic effects of a restricted number of plants, which constitute a genetically heterogeneous population, are considered.

High-Frequency Low-Penetrance Alleles

2009
Breast cancer, like other common cancers, tends to cluster in families, with disease being approximately twofold more common in first-degree relatives of cases [1–3]. The higher rate of most cancers in the monozygotic twins of cases than in dizygotic twins or siblings suggests that most of the familial clustering is the result of genetic variation ...
