(A) The Allele and Phenotype Query Form permits queries based on Phenotype Classifications. In this example, the Phenotype Classification ‘tumors, increased incidence’ and Allele Type ‘Transgene induced (gene targeted)’ with only Conditional mutants returned. (B) The query presented in panel A returns a summary page of alleles defined by the criteria in A. In this case, 8 alleles met the criteria. The symbol, name and molecular description of these alleles are provided. Links are provided to the detail pages for each allele. (C) The top part of the detail page for the mutant phenotype of Brac1^tm2Cxd details the Phenotype Classification terms for this particular mutation. Here, the details of the genotype that underlie the phenotype are represented. Each Phenotype Classification term is associated with one or more allele pairs and with the information known about the remaining genetic background. Thus, phenotypes are associated with genotypes, rather than simply with the allele.
