If your reference data has unphased or missing genotypes, you can create a phased reference panel by running Beagle on the unphased reference data (use the gtargument). Use of a population-matched reference panel can increase analysis accuracy.

WebJul 12, 2024 · A phased genotype at a genetic locus is an ordered pair consisting of a maternal and paternal allele at the locus. So to any heterozygous unphased genotype, there are two corresponding phased genotypes, and these two phased genotypes have equal frequencies under Hardy-Weinberg equilibrium. WebGenotype vs. Phenotype. The genotype of an organism is the genetic code in its cells. This genetic constitution of an individual influences – but is not solely responsible for – many of its traits. The phenotype is the visible or …

WebSometimes it is useful to combine a phased reference panel with an unphased reference panel when imputing genotypes in a study. For example, Howie et al.
