Figure 2
C-banding and C 0 t -1 DNA fractions in female mitotic chromosomes. The species names and the types of sex chromosome determination systems are indicated in each figure. Inserts show the locations of C-banding and C 0 t-1 DNA fractions in the neo-sex chromosomes during meiosis. Note the absence of the C 0 t-1 DNA fraction in the neo-Y chromosome of D. lilloanus. Bar = 5 μm.
