| Primary Identifier | MGI:2152904 | Allele Type | Spontaneous |
| Gene | T | Inheritance Mode | Semidominant |
| Strain of Origin | C57BL/6J | Is Recombinase | false |
| Is Wild Type | false |
| description | Tailless progeny were produced by a cross of mice heterozygous for Tl2 and for tw5, demonstrating that Tl2 is an allele of T (brachyury); it has therefore been renamed brachyury 9 Jackson (T9J). A cross to qk (quaking) produced no progeny having the quaking phenotype, indicating that if the T9J mutation, like most dominant T alleles, is a deletion, it does not extend as far distally as the qk locus (5.4 cM). |
| molecularNote | A spontaneous mouse mutant phenotypically similar to brachyury. A complementation test with tw5 was used to demonstrate allelism. |
