| Chromosome staining/banding/FISH |
C-banding revealed pericentromeric heterochromatin distribution in most chromosomes, and a large block on short arm of chromosome pair 8. 18S rDNA sites found on short arm of pair 8 (coincident with secondary constriction) and multiple sites of 5S rDNA on short arms of pairs 10, 23, 24, 25, 28, 29, 31 and 32. |
