Sentence examples for missing genotypes to from inspiring English sources

Genotype imputation allows different marker panels to be combined and missing genotypes to be infered in silico.

Initially we only used markers with no missing genotypes to create the framework linkage maps; markers with missing data were added manually later if possible.

We did not exclude individuals with some missing genotypes to prevent the loss of important information when looking at joint effects between polymorphisms.

Costs of genotyping are decreasing rapidly, and imputation using less dense marker sets allows the missing genotypes to be obtained almost for free.

Second, a preliminary 10-5 map was constructed from loci that had less than 12.5% missing genotypes to help define a starting marker order.

Bitwise data structures: SNP genotype data are converted into Boolean bit values and stored in memory-efficient Java BitSet arrays allowing missing genotypes to be handled easily.

If fewer than eleven reads were present, we assigned a missing genotype to avoid misclassifying a triplex heterozygote.

Analyses were performed to impute the most likely values of missing genotypes, and to calculate posterior genotype probabilities at all HapMap SNPs.

Two different filtering criteria were used for the CEGS SNP calls, 1) All filtered SNP calls with missing genotypes assumed to be reference and 2) All filtered SNP calls with an additional MAF filter of 5%% and imputed missing genotypes.

We reapplied quality checks to these marker data, excluding markers with (i) a rate of missing values above 5%% and (ii) allele frequencies smaller than 0.05 or larger than 0.95, and complemented missing genotypes according to a binomial distribution.

Common approaches for dealing with missing genotypes are to replace them with estimated values, either using imputation [ 13] or more simply, by their population expected values (2 p), sometimes referred to as 'naïve imputation' [ 14].
