Abstract
One hundred and four H-2 congenic lines were typed for alleles at seven loci, Qa-1, Qa-2, Tla, C3, Ce-2, Pgk-2, and Upg-1, residing distal to the H-2 complex. The results of the typing were used to estimate the length of the segment of chromosome 17 derived from the donor strain of each line—that is, the minimal length of the differential segment. The results indicate that only lines derived by intra-H-2 crossing-over in such a way that they inherited the right-hand portion of H-2 from the inbred partner have the telomeric half of chromosome 17 identical with that of the inbred-partner strain. In other lines the differential segment is at least 3 to 10 cM long. It is argued that in some lines the entire telomeric half of chromosome 17 might be of donor-strain origin.Keywords
