Sentence examples for based on genotype frequencies from inspiring English sources

Population attributable risk percentage (PAR) for the risk genotypes (SNP rs5770917 C/C and T/C) was evaluated using the following formula, PAR = [p RR 1)]/[p RR 1)+1]), where p is calculated based on genotype frequencies in healthy controls and RR indicates relative risk of the risk genotypes.

Using a population genetic model based on genotype frequencies as an example, we propose a set of methods to assist in the computation and interpretation of big, dense Markov chain transition matrices.

For the χ2 test based on genotype frequencies, MCB always leads to power loss in all scenarios under different disease models compared with the null (in the absence of missing) (see Fig. 2 and Additional file 2).

For χ2 test based on genotype frequencies, genotyping errors may have no effect on association studies sometimes, i.e., in Scenario I and Scenario II for the dominant disease model (h AA = h Aa ≠ h aa ); otherwise, it may cause power loss.

Table 3 reports the crosstabulation of genotype frequencies according to lymph node and tumor-derived DNA, the kappa statistic for agreement between the two tissue types, and results from Chi-square tests for Hardy Weinberg equilibrium based on genotype frequencies from the normal tissue samples.

Genetic diversity was evaluated based on genotype and allele frequencies, the level of polymorphism, and the observed and unbiased expected heterozygosity (HO and HE) using genetix 4.04 (Belkhir et al. 2002).

Our data demonstrated 100% concordance between the two different specimens, except a discrepancy in one sample for the miR-146a SNP (Table  1, Additional file 1: Table S5).> After adjustment for confounding factors (sex and age), the results of the risk estimation analysis based on genotype distribution, allele frequency, and genetic model by logistic regression analysis are shown in Table  2.

One example is the model presented in [ 16]: an extension of a classic biallelic Wright-Fisher model, it is based on genotype rather than allele frequencies.

The SNP 'call rates' (the proportions of individuals with at least one sequence read at each SNP position) and their minor allele frequencies (MAFs), based on genotype calls, were calculated.

The data required for single locus segregation analysis are four-fold: 1) a pedigree relating individuals to each other; 2) phenotypes on some individuals in the population; 3) a penetrance function expressing the probabilities of phenotype based on genotype; and 4) estimates of the frequencies of the genotype alleles in the population.

Therefore, statistical software is used to estimate the haplotype frequencies in a population based on genotype data and LD.
