'''C-value''' is the amount, in [[picogram]]s, of [[DNA|DNA,]] contained within a [[haploid]] [[Cell nucleus|nucleus]] (e.g. a [[gamete]]) or one half the amount in a [[diploid]] [[somatic cell]] of a [[eukaryotic]] organism. In some cases (notably among diploid organisms), the terms C-value and [[genome size]] are used interchangeably; however, in [[Polyploidy|polyploids,]] the C-value may represent two or more [[genome]]s contained within the same nucleus.
