Inter and intraspecific variation in nuclear DNA content in Aedes mosquitoes.
Haploid nuclear DNA of 23 species of Aedes, as determined by Feulgen cytophotometry, was found to vary 3-fold. This was accompanied by a 2-fold variation in total chromosomal length. There was a significant correlation (r = 0.765, P less than 0.001) between these two parameters. Genome size varied from 0.87 pg to 1.3 pg among 10 strains of Aedes albopictus, from wide geographic regions. Large scale differences in chromosomal DNA amounts have accompanied speciation and evolution in aedine mosquitoes.
