The 'A' allele frequency was 40% and 33.58% while 'T' allele frequency was 60% and 66.42% in the control and GDM groups respectively.
Allele frequency percentages for 15 autosomal STR loci in 100 samples from Khuzestan province population of Khuzestan province in Iran.
We also used the same software to examine allele frequency distributions for a mode-shift suggesting recently bottlenecked populations.
Screening blood samples from 78 breeding emus revealed 14 (18%; 9 males, 4 females, and 1 unknown gender) carriers; an overall 0.09 mutant [alpha]-N-acetylglucosaminidase allele frequency. A "test and cull male carriers" program, in which carrier males are culled but carrier females are retained, was proposed to avoid breeding affected emus together, ultimately eliminating the disease from future broods, and preserving the gene pool with as much breeding stock as possible.
The SNPs were filtered statistically with a minor allele frequency <5% and the allele frequencies of each SNP were examined to evaluate the associations with plumage colors using Fishers exact test by using PLINK software version 1.07 [14] at the p<0.05 level of significance.
Based on the results, for most alleles there was no stable change in allele frequency (Figure 3); only in three markers (9%) was the change in allele frequency significantly adjusted for linear regression (Umc1714 (p < 0.01), Umc1506 (p < 0.01), and Umc1071 (p < 0.10)).

Concerning the TM6SF2 rs58542926 polymorphism, an increase of the T allele frequency was observed in patients with NASH cirrhosis with respect to healthy subjects, while the comparisons between the other groups did not yield statistically significant differences.
Currently, there are no studies in the Mexican population using direct sequencing on the relationship between HLA class I allele frequency and susceptibility to influenza virus A H1N1/09 infection.
Since ethnic variation in allele frequency is widely documented, [3,8] population specific data of VDR polymorphism has to be generated before conducting a valid genetic association study.
