Genome Size Estimation and Quantitative Cytogenetics in Insects Chapter uri icon


  • With care, it is possible using flow cytometry to create a precise and accurate estimate of the genome size of an insect that is useful for genomics, genetics, molecular/cell biology, or systematics. Genome size estimation is a useful first step in a complete genome sequencing project. The number of sequencing reads required to produce a given level of coverage depends directly upon the 1C amount of DNA per cell, while an even more critical need is an accurate 1C genome size estimate to compare against the final assembly. Here we present a detailed protocol to estimate genome size using flow cytometry. Published genome size estimates should be submitted to genomesize.comso that they are available to all.
