Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]
Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

The article presents the comparative results of the experimental work on studying valuable pure species offspring (white sturgeon, fringebarbel sturgeon) and their interspecies hybrid forms (white sturgeon × fringebarbel sturgeon and fringebarbel sturgeon × white sturgeon) in the early stages of ontogenesis.
