Telomerase activity has been found in the somatic tissues of rainbow trout. The enzyme is
essential for maintaining telomere length but also assures homeostasis of the fish organs …

Contents Gynogenetic and androgenetic brown trout (Salmo trutta Linnaeus 1758) haploids
(Hs) and doubled haploids (DH s) were produced in the present research. Haploid …

The purpose of this work was to quantify the impact of spontaneous and X-radiation-induced
chromosome rearrangements on survival rate of androgenetic rainbow trout (Oncorhynchus …

In fish with the XX/XY sex determination system, the production of all-female offspring within
one generation was achieved by gynogenesis. Successful induction of gynogenesis in the …

The study provides new data on the stability of gamma radiation-induced chromosome
fragments of a putative maternal nuclear genome in an androgenetic vertebrate, rainbow …

The method of ploidy level determination depends on the equipment, expertise of the lab or
farm staff, and on the material studied (fish species, specimens' age and size, etc.). The …

Ionizing radiation is administered to damage nuclear genome in fish eggs during induced
androgenesis. In this study, we examined whether 350 Gy of X-ray applied to damage …
