The Sharp complex is one of the best things in the Boa breeding hobby.
You have the Sharp albino, Boa woman caramel and the prodigy all of which are on the same allele. When Sharp and Boa woman caramel are bred together you get paradigm boas. A visual intergrade between the 2 mutations, effectively het for Sharp and het for Boa woman caramel. When you breed Sharp to prodigy you get paradise Boas, similarly to the paradigm. Prodigy and bwc appear to be unique from one another, whether that is due to polygenic differences or whether they happen to be similar mutations that arose independent of one another is unknown.
