DISPLAY OF ESTIMATED PARENTAL CONTRIBUTION TO ANCESTRY

Estimating parental contribution of ancestry includes: obtaining a set of ancestry assignment data associated with an individual's genotype data, at least some of the ancestry assignment data indicating that one or more segments of the individual's genotype data is deemed to be associated with a specific ancestry; determining whether in the individual's genotype data there is at least one confirmed region of overlapping ancestry assignment associated with the specific ancestry; in the event that it is determined that there is at least one confirmed region of overlapping ancestry assignment associated with the specific ancestry: specifying that parental contribution of the specific ancestry is made by both parents of the individual; in the event that it is determined that there is no confirmed region of overlapping ancestry assignment associated with the specific ancestry: statistically determining whether the parental contribution to the specific ancestry is made by only one parent of the individual or by both parents of the individual, the determination being based at least in part on one or more lengths of the one or more segments deemed to be associated with the specific ancestry; and outputting information pertaining to the parental contribution to the specific ancestry.
