G-banding patterns reveal that several human chromosomes differ from those of chimpanzees by only a pericentric inversion.

An inversion may break a gene into two parts, with one part moving to a new location and destroying the function of that gene.

 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.

Inversion homozygous - No special problems arise in meiosis. Inversion heterozygous - Two chromosomes form an inversion loop
