The New World Artemia species A. franciscana and A. persimilis are highly differentiated for chromosome size and heterochromatin content.

abstract：BACKGROUND:Until recently, mechanisms of segmentation established for Drosophila served as a paradigm for arthropod segmentation. However, with the discovery of gene expression waves in vertebrate segmentation, another paradigm based on oscillations linked to axial growth was established. The Notch pathway and hairy de...
