MII spreads of an individual, heterozygous for nr chromosome, with 24 chromosomes in somatic cells. (a) The MII cell with 11 chromosomes, arrows indicate p and q acrocentrics. (b) The MII cell with 12 chromosomes, arrows indicate p, q and Y1 acrocentric chromosomes. (c) The MII cell with 12 chromosomes, arrows indicate four acrocentrics n, p, q and r. (d) The MII cell with 13 chromosomes, arrows indicate n, p, q, r and Y1 chromosomes. MII, metaphase II.
