> Abstract
> A cytogenetic study of the activity of the embryonic genome in
> ferret (Mustelaputorius) blastocysts during 6 days after their
> transition from the oviduct to the uterus has been carried out. It
> has been found that the prolongation in the preimplantation period
> in the ferret is not accompanied by inhibition of mitosis or
> activity in nucleolus organizing regions of inner cell mass cells as
> occurs in species having an obligatory delay of implantation
> (obligate embryonic diapause). Amitosis of trophoblast cells starts
> at the periimplantation stage as in other species that do not have
> obligate diapause. The data obtained are consistent with the
> hypothesis that the obligatory stage of delayed implantation might
> occur in some mammals in different taxonomic groups as a result of
> chromosome mutations affecting the genetic control of the chronology
> of events (timing) of embryogenesis. Consequently the
> characteristics of delayed implantation should be different in
> different species.
