STR Allelic Frequencies in a German Skeleton Collection
Anthropologischer Anzeiger, 2000Chromosomal DNA was isolated from bones from a German skeleton collection (Goslar, 18th century) and detected by PCR. Nine microsatellite regions were amplified by multiplex reactions using the AmpFlSTR Profiler Plus kit and analysed to obtain their allelic distribution.

Random variation of allele frequencies
1995In 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.

Estimating allele frequencies of hypervariable DNA systems
Forensic Science International, 1991Several 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.

Polymorphism of the h allele and the population frequency of sporadic nonfunctional alleles
Transfusion, 1997BACKGROUND: Current polymerase chain reaction‐based strategies for phenotype prediction often fail when sporadic nonfunctional alleles are encountered. The population frequency of such mutations was not known for any gene under low selection pressure and may be best examined in blood group systems lacking prevalent nonfunctional alleles.

Apolipoprotein E allelic frequency in elderly smokers
American Journal of Medical Genetics, 1998Susceptibility 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.

Frequency of HLA DQA1 alleles in an Italian population
International Journal of Legal Medicine, 1992A sample of 103 Italians was tested for HLA-DQA1 polymorphism using the polymerase chain reaction (PCR) and dot blot hybridization. Results were in Hardy-Weinberg equilibrium. The power of discrimination was 0.91 and the rate of exclusion 56.7. The frequencies of the DQA1*0201 and DQA1*0301 alleles were found to be significantly different from other ...

On the description of changes in allele frequency
1990Following on our discussion of models in the last chapter, we should now be in a position to attempt a mathematical description of changes in allele frequency over successive generations. We are, however, faced with an immediate difficulty, to the resolution of which the present chapter is devoted: which description is most appropriate?
