| constitutive heterochromatin in karyotypes of two cicadidae species from japan (cicadoidea, hemiptera). | karyotypes of males of cicadas tibicen bihamatus (motschulski) and platypleura kuroiwae matsumura were studied using c-banding technique. in tibicen bihamatus two types of c-band distribution were observed. two chromosome pairs have c-bands at one of the chromosome ends, while in the other, including the sex chromosome, c-heterochromatin blocks occurred at both ends. platypleura kuroiwae has a smaller amount of c-heterochromatin located as small subterminal blocks. the intercalar c-bands were se ... | 2002 | 12729170 |
