Position-effect variegation — is a variegation caused by the inactivation of a gene in some cells through its abnormal juxtaposition with heterochromatin.The classical example is the Drosophila w [m4] (speak white mottled 4) translocation. In this mutation, an inversion on… … Wikipedia
Position effect — is the effect on the expression of a gene when its location in a chromosome is changed, often by translocation. This has been well described in Drosophila with respect to eye color and is known as position effect variegation (PEV). [cite journal… … Wikipedia
