The genome size (GS) and AT base pair content of thirteen species of Decapoda belonging to different genera (nephrops, homarus, Palinurus, Jasus, Scyllarides, Scyllarus, and Aristeomorpha) from four families (Nephropidae, Palinuridae, Scyllaridae, and Aristeidae) were determined by flow cytometry. A high variability of DNA content has been observed. The percentage content of AT in the studied species ranges from 34.92 in Homarus americanus to 47.46 in Palinurus elephas and most species have a value of about 40%. in the family Scyllaridae, tyhe correlation between DNA content and chromosome number supports the hypothesis of polyploidization events during karyotype evolution.

Abstract
The genome size (GS) and AT base pair content of thirteen species of Decapoda belonging to different genera (nephrops, homarus, Palinurus, Jasus, Scyllarides, Scyllarus, and Aristeomorpha) from four families (Nephropidae, Palinuridae, Scyllaridae, and Aristeidae) were determined by flow cytometry. A high variability of DNA content has been observed. The percentage content of AT in the studied species ranges from 34.92 in Homarus americanus to 47.46 in Palinurus elephas and most species have a value of about 40%. in the family Scyllaridae, tyhe correlation between DNA content and chromosome number supports the hypothesis of polyploidization events during karyotype evolution.
