t-Complex Genome Region

**Definition:** A 20 cM region of mouse chromosome 17 that is represented by a least two HAPLOTYPES. One of the haplotypes is referred to as the t-haplotype and contains an unusual array of mutations that affect embryonic development and male fertility. The t-haplotype is maintained in the gene pool by the presence of unusual features that prevent its recombination.
