Journal ArticleDOI
The biochemistry of differentiation of mouse trophoblast: studies on polyploidy
TL;DR: That earlier developmental events such as the formation of the blastocoel cavity may in some way trigger polyploidization of trophoblast is not inconsistent with the studies described.
Journal ArticleDOI
DNA synthesis in the preimplantation mouse embryo.
TL;DR: It was concluded that the development of excess DNA amounts does not depend on the maternal environment and these nuclei which contained greater than 4 C amounts of DNA were labelled after short exposures to radioactivity, and it was likely that they were becoming polyploid.
Journal ArticleDOI
Meiosis and B-Chromosomes in Listera Ovata (Orchidaceae)
Canio G. Vosa,Peter W. Barlow +1 more
TL;DR: It is suggested that B-chromosomes prolong the time available for chiasma formation allowing the utilization of more sites for chIASma formation so accounting for the rise in chiasm frequency.
Journal ArticleDOI
The effect of supernumerary chromosomes on meiosis in Puschkinia libanotica (Liliaceae)
TL;DR: The pattern of chiasma distribution along each of the five A bivalents was related to the DNA labelling pattern of mitotic chromosomes, and Regions that showed heavy labelling at the end of the DNA synthetic phase had fewer chiasmata than lightly labelled regions.
Journal ArticleDOI
The chromosomes of Puschkinia libanotica during mitosis
TL;DR: Microdensitometry of metaphase chromosomes shows that the segment of the B chromosome that is heterochromatic during interphase has no more DNA per unit volume than any of the euchromatic A chromosomes.
