One of the assignments I give my intro biology students is called “Dragon Genetics,” in which they determine the alleles (versions of genes) that a baby dragon will inherit from its parents. Then, I ask them to create an accurate image of the dragon, based on the inherited traits. Most of the students use a dollmaker (from this site). Here’s one I created as an example:

I love to see their dollmaker dragons, but occasionally, I’ll have a few students who do the artwork entirely by hand. Here are some examples from this semester:

Pretty spectacular, eh?
