#Unit 2. Cellular Organization
An actual overlapping gene occurs when the same sequence of DNA encodes two nonhomologous proteins because it uses more than one reading frame.
#Id: 535
We use the principle of parsimony in comparing the organization of orthologous genes by assuming that a common feature predates the evolutionary separation of the two species.
