Heterochromatin variation in artemia populations

The genus Artemia is an interesting model organism for evolutionary studies since many factors driving speciation have been observed in the genus. It has been suggested that in this genus heterochromatin content could be a reliable criteria to establish taxonomic identity of populations. In the pres...
