Karen, I'm so sorry. I missed your second question. Half-identical Region (HIR) - a region or segment along one of the copies of a chromosome (chromosomes each have two copies, one from mom and one from dad) where at least one of the two alleles (A, G, T, C) of a person's test results matches at least one of the two alleles from a different person's test results throughout the segment. A half-identical region may be either identical by descent (IBD) or identical by state (IBS). -----Original Message----- From: autosomal-dna-bounces@rootsweb.com [mailto:autosomal-dna-bounces@rootsweb.com] On Behalf Of Karen Hodges Sent: Saturday, October 19, 2013 2:29 PM To: autosomal-dna@rootsweb.com Subject: Re: [AUTOSOMAL-DNA] Family finder matches what to make of them Hi Emily I was wondering what a mish mash of paternal and maternal alleles was? . Your comment is much appreciated. What is HIR short for please?
