The shorter and longer arms of a submetacentric chromosome are referred to as :- (1) s-arm and l-arm respectively (2) p-arm and q-arm respectively (3) q-arm and p-arm respectively (4) m-arm and n-arm respectively

Model Answer:

2. p and q are shorter and longer arms of a sub-metacentric chromosome. Submetacentric chromosomes have the centromere slightly offset from the center leading to a slight asymmetry in the length of the two sections. Human chromosomes 4 through 12 are submetacentric in nature.
