9. Integration in MGI Identifying objects. Resolving or noting discrepancies. Integration is key to knowledge discovery in age of genomics in age of genomics

10. The Power Of Integration: Queries What transcription factors are expressed in a 2-cell embryo and not in a blastocyst? What transcription factors are expressed in a 2-cell embryo and not in a blastocyst? integration of multiple expression assay data sets and data types. integration of multiple expression assay data sets and data types. standardization of anatomical references and developmental stages standardization of anatomical references and developmental stages What development QTLs contain these TFs? What development QTLs contain these TFs? integration of expression data and mapping data integration of expression data and mapping data genetic map result of integrating lots of mapping data genetic map result of integrating lots of mapping data What strains are distinguished by SNPs in this region? What strains are distinguished by SNPs in this region? And so on… And so on…
