In an Inversion, a Segment of a Chromosome Is Turned

Multiple Choice

In an inversion, a segment of a chromosome is turned 180 degrees. Inversions cause breaks in some genes and may move others to new locations. In individuals heterozygous for a chromosome inversion, the homologous chromosomes form a loop in prophase I of meiosis. When crossing over takes place within the inverted region, nonviable gametes are usually produced, resulting in a depression in observed recombination frequencies.
-A dicentric chromosome is produced when crossing over takes place in an individual heterozygous for which type of chromosome rearrangement?

A) Duplication
B) Deletion
C) Paracentric inversion
D) Pericentric inversion
