Müllerian mimicry is a form of biological
resemblance in which two or more dangerous or toxic organisms exhibit similar
warning systems. These organisms, that may or may not be closely related, facilitate
predator learning by mimicking each other’s warning signals, such as the same brightly colored wing
pattern, to their mutual benefit. Because a predator that has
learned to avoid an organism with a given warning system will avoid
all similar organisms, the resemblance between Müllerian mimics acts as a
protective mechanism for participating organisms. Through a variety of
technical approaches in developmental genetics and the construction of genetic
linkage maps, researchers determine gene expression and selective agents as sites
that controls phenotypic traits related to mimicry
