C0t-1 DNA fraction hybridization in metaphase I chromosomes of 0B individuals (a) and 1B individuals (b,c). Ideogram (d) showing the hybridization patterns described in this work. The arrows indicate the sex bivalents (Xyp), arrowheads indicate the B chromosome, and the * (asterisk) indicates the chromosome pairs with additional heterochromatic blocks. Bar=5 μm.
