The P-Arm and Q-Arm are Determined by the Location of the Centromere

Question

The p-arm and q-arm are determined by the location of the centromere.

Accepted Answer

The centromere determines the placement of the p-arm and q-arm on a chromosome. The p-arm is the shorter arm, located on the side of the centromere closest to the top of the chromosome. The q-arm is the longer arm, located on the side of the centromere closest to the bottom of the chromosome.
