Chromosomal Changes

Question 14 • FL-2000310-Biology 1 Sem 1 - Flex

A chromosome has an inversion. Which describes a pericentric inversion?

Answer
A
deletion of genes within the same chromosome arm
B
switching of genes within the same chromosome arm
C
switching of genes around the centromere
D
deletion of genes around the centromere

Explanation

An inversion occurs when a chromosome segment breaks off, turns around, and reattaches. A pericentric inversion includes the centromere, so it switches the order of genes on both sides of the centromere. Therefore, the correct choice is switching of genes around the centromere.
