Haplarithmisis (Greek for haplotype numbering) is a conceptual process in Genetics that enables simultaneous haplotyping and copy-number profiling of DNA samples derived from cells. Haplarithmisis also reveals parental, segregation, and mechanistic origins of genomic anomalies.[1][2] The resulting profiles of haplarithmisis are called parental haplarithms (i.e. paternal haplarithm and maternal haplarithm).
