Pigmentation patterns result from the local conversion of precursor metabolites into pigment deposits by several enzymes (Wittkopp et al., 2003). The expression patterns of these enzymes, generally specified at an advanced developmental stage when the overall morphology closely resembles the adult layout, are the blueprints of the visible pigmentation patterns (Wittkopp et al., 2002a). Therefore, understanding how the expression patterns of the genes encoding these enzymes are established and change among species is key to understanding the formation and diversification of pigmentation patterns.

As of 2013, the National Science Education Standards have been replaced by the Next Generation Science Standards (NGSS), available as a print book, free PDF download, and online with our OpenBook platform.
The NGSS offer a detailed description of the key scientific ideas and practices that all students should learn by the time they graduate from high school. The standards are based largely on the 2011 National Research Council report A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas.
