WebMolecular mimicry is thus occurring between two recognized peptides that have similar antigenic surfaces in the absence of primary sequence homology.

WebIn species with extremely recent common ancestors (humans and chimps, for example) a high percentage of mutations are shared. This is called a sequence homology, because it’s a shared sequence from a common ancestor. In guinea pigs, the mutation that deactivated GLO happened independently.
