[i] Telocentric indicates that the centromere is at the proximal region of the chromosome. Acro/rDNA indicates an acrosomal centromere with rDNA's in the acrocentric arm. Metacentric indicates a meta- or submetacentric centromere. Telomere size (kbp) is estimated as the number of telomeric bases composed of hexamer repeat sequences.
