To summarize, the cell subtype percentages of zygotene and diplotene for CBZ-, IPR- and CCK-treated cell cultures followed the same decreasing trend compared with controls.
1976) chiasma terminalization is 'a progressive shift between diplotene and metaphase I in the distribution of chiasmata along the arms of bivalents from their points of origin to more distal positions'.
As the behavior between XR and Y during diplotene and diakinesis are different in the species of both genera, it seems that the X-A fusion has occurred independently in two ancestral species of each genus.
In the prophase of first meiotic division, the large majority of diplotene stages show XR and Y in contact at the distal end (Fig.
Se distingue en el citosol un notorio cuerpo vitelino o de Balbiani, con numerosas vacuolas a su alrededor, mientras que, en el interior del nucleo se observan los cromosomas en diplotene con configuracion Lumpbrush (Fig.
This phase of meiosis is completed only to the diplotene stage.
Primary oocyte growth (size ~ 25-270 [micro]m): The first phase of oocyte growth starts with the arrest of meiosis in diplotene.
In the diplotene cells, the occurrence of an interstitial chiasma was observed in three bivalents, in the cells with 15 = 7II + X, and in six bivalents, in the cells with 30 = 14II + 2X.
The primary spermatocyte consists of 5 stages: leptotene (LSc), zygotene (ZSc), pachytene (PSc), diplotene (DSc) and metaphase (MSc) (Figs.
