Final answer:
A chromosome with a centromere that creates arms of uneven lengths is known as a chromosome.
Step-by-step explanation:
A chromosome with a centromere located such that one arm of the chromosome is longer than the other arm is called a submetacentric chromosome. In these types of chromosomes, the centromere is positioned off-center, resulting in one arm being notably longer than the other, distinguishing it from a metacentric chromosome which has arms of approximately equal length. The classification is based on the location of the centromere and the subsequent lengths of the p (short) and q (long) arms.submetacentric
submetacentric chromosomes have their centromere positioned close to one end, creating a shorter arm and a longer arm. One example of an submetacentric chromosome in humans is chromosome 13.
