Here we present the beginning of the Redhead Genome Project scarf from She Dances in Dragon. She researched the mutations in the MRC1 gene thought to cause red hair, and charted the alleles as shown in the top part of the photo. G is black, C is blue, T red and A green, as per standard coloring for DNA bases. The DNA is charted 30 bases across a row, so it is even possible that the codons are together.
She Dances in Dragon generously made her charts available:
