In the Brooder
interestingly, Chicago pigeons also have the highest frequency of the spread phenotype of any sampled area. While the allele for this plumage type is dominant and epistatic to most patterns, it is usually quite rare. Stunningly, about 10% of the sampled population of Chicago showed the spread phenotype...of course, we don't quite know why that is, but it may have something to do with the heat-absorption properties of dark plumage.
