Scientist play “color the butterfly”

I’m not talking about coloring books, or the new adult coloring fad, but rather new possibility in the using the CRISPR-cas gene editing.

The patterning and colors on butterflies’ wings are governed by suites of genes. Crispr-Cas now makes it much easier to figure out what a gene does by deleting it and seeing what happens.

Two teams of biologists report in The Proceedings of the National Academy of Sciences that they have used the technique to explore the roles of two master genes that control the appearance of a butterfly’s wings.
