| The reason is that homologous pairing takes place before metaphasis, during pachytene. |
| This SC karyotype is very similar to karyotypes developed from pachytene chromosome squashes. |
| In wild-type hermaphrodites, germ cells at the dorsoventral flexure exit the pachytene stage of the first meiotic prophase and proceed to diakinesis. |
| This structural heterozygosity correlates with both a previously described recombination block and cytologically visible unpaired chromosomes at pachytene. |
| Zygotene and pachytene chromosomes can be distinguished by their different morphology due to the extent of synapsis. |
| In addition, Creighton used pachytene stage chromosomes to continue deletion mapping studies. |
