Question

In a pericentric inversion, where is the centromere located relative to the inversion loop?

Options

• Inside the inverted segment

• Split into two separate centromeres

• Outside the inversion loop

• Attached to the telomere of the chromosome

Answer 1

A pericentric inversion includes the centromere within the inverted segment (inversion loop). This inclusion of the centromere is the defining feature that distinguishes pericentric from paracentric inversions.
