showed that the mean calcium levels were higher in breast cancer patients compared to controls (P< 0.001) due to inactivating polymorphisms at rs1801725.23 Moreover, a research performed on Iranian CRC patients showed that CASR gene (rs1801725) variant is not a genetic contributor to CRC risk in the Iranian population.13 In another case-control study that was conducted to explore the possible association between (rs1801725) variant in CASR gene and CRC risk, they found no significant difference for this variant in both genotype and allele frequencies between CRC and the controls.24
The GLS method with sparse matrices, is very fast and highly accurate, for estimating base generation allele frequencies compared to the current method.
Conclusion: Higher serum vaspin levels were seen in gestational diabetic females, but genotype and allele frequencies showed no association of vaspin with gestational diabetes mellitus.
This study was performed to analyze STR genotypes, report their allele frequencies and evaluate their application among the Table 1.
The comparison of the allele frequencies in the present investigation with those in other populations was made using the chi-square test.
Least squares means and standard errors for carcass traits of genotypes in CALN and their Genotype and Allele frequencies.
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.
To understand the genetic variation during selection cycles, estimating the proportion of heterozygotes in the populations is important to ensure the progress of the selection of traits of interest for the crop, as alterations in allele frequencies due to selection may lead to biased estimates and reduce the degree of polymorphism and expected heterozygosis (Choudhary et al., 2012; Sarcevic, Pejic, Baric, & Kozumplik, 2007).
The M and N allele frequencies were higher and lower respectively in Lori (63.8 and 36.2) (Asadi et al., 2012), Dalagh (55.5 and 44.5), (Azari et al., 2012), Thalli, Atabi (81.0 and 19.0) (Suleman et al., 2012; Nanekarani et al., 2011), Polish-Merino (76.2 and 23.8), Blackhead mutton (81.4 and 18.6) (Szkudlarek-Kowalczyk et al., 2011) and Iranian Karakul (79.0 and 21.0) (Shahroudi et al., 2006) sheep breeds.
We compared genotype and allele frequencies of each of 9 genes' SNPs (TLR2 G753A, TLR4 C399T, TLR9 G2848A, TGF-[beta]1 C509T, PGR PROGINS, IL-6 G174C, IL-8 C781T, IL-10 C592A, and TNF[alpha] G308A) in 106 women with spontaneous abortion and in the control group of 74 women who delivered in term (Figure 1, Tables 1-18).
