Karyotype Data

Cytogenetic data is perhaps the most basic information about a genome (i.e., how many discrete chromosomes is the genome divided among, what type of sex chromosomes are present). Despite the fundamental nature of this data, many questions surrounding the evolution of genomes at this level remain unanswered. Furthermore, as we move into an era of ever more affordable sequencing, this is critical preliminary information that should be evaluated before sequencing and may even suggest particularly attractive targets for future sequencing efforts. Unfortunately, cytogenetic data is often scattered among many journals and often behind paywalls. For these reasons, we have built databases that make this data publicly available.
Amphibian Karyotype Database
2124 records
Coleoptera Karyotype Database
4960 records

Polyneoptera Database
823 records
Diptera Karyotype Database
3443 records
Drosophila Karyotype Database
1247 records
Mammal Karyotype Database
1440 records

These databases are supported by the Blackmon Lab at Texas A&M University and the Demuth Lab at The University of Texas at Arlington.
