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


deletion of genes within the same chromosome arm

switching of genes within the same chromosome arm

switching of genes around the centromere

deletion of genes around the centromere

Verified Answer :

deletion of genes around the centromere

The correct answer for this question would be the fourth option. Deletion of genes around the centromere is considered a pericentric inversion. The Pericentric inversions include the centromere and there is a break point in each arm. Deletions and duplications occur during crossing over during the inversion which results in recombination in two loops.
