Genetic characterization and intra-generic relationships of Artemia monica Verrill and A. urmiana Günther

摘要: Allozyme variation encoded for by 22 enzyme loci analyzed with starch-gel electrophoresis from samples of gonochoristic Artemia monica and A. urmiana collected Lake Urmia, Iran Mono Lake, CA, USA, respectively, are compared contrasted data representative populations franciscana, persimilis salina, as well diploid, triploid, tetraploid, pentaploid parthenogenetic forms. Values parameters measuring degree genetic variability (number alleles per locus, proportion polymorphic loci, expected heterozygosity) in were among the highest genus (1.76, 0.46, 0.19, 2.19, 0.55, 0.14, respectively). For monica, possible factors promoting its high discussed. Mean values Nei's D between franciscana very low (0.09) consistent reported cytological morphological similarities, thus physiological differentiation which distinguishes former must involve differences at few loci. to rest species (≥0.95) taxonomic status distinctive morphology, while distance monophyletic lineage (mean = 0.48) suggests a recent common ancestry.
