 If their positions are altered by an inversion, their expression may be altered, an outcome referred to as a position effect.

#Unit 8. Inheritance Biology

An inversion moves a wild-type allele (red eyes) at the white locus in Drosophila to a chromosomal region that contains highly condensed, the wild-type allele is not expressed in some cells, resulting in an eye consisting of red and white spots.
