| Asynapsed trivalents | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | Total | % | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Ectopic associations | none | 35 | 1 | 3 | 4 | 3 | 2 | 0 | 0 | 0 | 47 | 33,6 |
| XY/triv | 2 | 13 | 8 | 6 | 8 | 3 | 0 | 0 | 0 | 38 | 27,1 | |
| triv/triv | 0 | 0 | 5 | 7 | 4 | 4 | 0 | 0 | 0 | 22 | 15,7 | |
| both | 0 | 0 | 0 | 3 | 9 | 12 | 3 | 2 | 3 | 33 | 23,6 | |
| Total nuclei | 37 | 14 | 16 | 20 | 24 | 21 | 3 | 2 | 3 | 140 | 100 |
140 nuclear microspreadings from 2n = 32 pachytene spermatocytes were examined.
The single axes and central element of the SC were identified by immunochemistry, using, respectively, anti-SYCP3 and anti-SYCP1 antibodies (as in Figure 5c & d).
