Karyological information |
||
| Geographical area of study | Göksu Delta & Orontes River, Turkey. | |
| Source of chromosomes | - |
|
| Number of specimens with sex | 20 (10 from Orontes River, 10 from Göksu Delta). |
|
| Diploid chromosome number | 56 |
|
| Karyotype formula | 24m+10sm+10st+12a (Orontes River), 28m+6sm+10st+12a (Goksu Delta). |
|
| Fundamental arm number | 100 |
|
| Chromosome length | - |
|
| Sex chromosome | - |
|
| Chromosome staining/banding/FISH | Multiple NORs observed in terminal region on short arm of submetacentric pair 13, long arm of subtelocentric pair 22, on long arm of acrocentric pairs 27 and 28. C-band-positive regions distributed in centromeric positions. Chromosome pairs 2, 3, 13, 14, 15, 16, 18, 23 showed larger C-band signals than other chromosomes. G-banding produced smaller blocks in pericentromeric and terminal regions of many chromosomes. |
