t⁴

A member of the t<9> complementation group that resulted from a rare recombination event between a complete haplotype and a wild-type chromosome. DNA probes obtained by microdissection and microcloning of fragments of mouse Chromosome 17 show that this allele comprises a deletion of D17Leh54,94,180 and 443,and a duplication of D17Leh89,467,and 525. This allele is a member of the t<9> complementation group and not found in wild populations. (J:8922)
