<mods:abstract>I am designing a program to be able to identify Identical by Descent (IBD) tracts
in unphased genotypes. In many cases, when genomes are sequenced, it can be difficult to
localize which fragments of known sequence belong on which of a set of complimentary
chromosomes, and as such, sequence data can be ambiguous. Usually this ambiguity is resolved
through phasing, where the each piece of known sequence is localized to one particular
complimentary chromosome via statistical estimates and knowledge of relationships between
sequences. Once done, it is possible to determine if two portions of DNA sequence in two
separate chromosomes share a common ancestral origin. However, the common ancestral origin
information (a.k.a. Identical By Descent) would be very useful for the statistics involved
in phasing, thus the ability to determine the tracts of Identical by Descent DNA sequence
would assist the statistical accuracy of the phasing if it could be done first. That is what
my program currently aims to accomplish, as efficiently in both time and memory
possible.</mods:abstract>
