  Y haplogroup analyses are an important component of genealogical
reconstruction, population genetic analyses, medical genetics and forensics.
These fields are increasingly moving towards use of low-coverage, high
throughput sequencing. However, there is as yet no software available for using
sequence data to assign Y haplogroup groups probabilistically, such that the
posterior probability of assignment fully reflects the information present in
the data, and borrows information across all samples sequenced from a
population. YHap addresses this problem.
