Induced development of haploid embryos (H) with only paternal (androgenesis) or maternal
(gynogenesis) chromosomes requires irradiation of eggs before fertilization or activation of …

In most fish species, morphologically distinct sex chromosomes are absent, and neither sex
determination genes nor sex‐related markers have yet been identified. Thus, induced …

Distant hybridization occurs widely in fishes and is a useful strategy to produce different
ploidy offsprings. In this study, we obtained androgenetic blunt snout bream (2n= 48 …

Somatic growth is considered to affect pace of the telomere attrition in vertebrates. As
normally developed and dwarf fish differ in the body size we have decided to compare …

The aim of the study was to determine the optimum temperature shock timing to induce
androgenetic and gynogenetic growth in common tench (Tinca tinca L.). UV radiation at the …

Contents Meiotic gynogenesis was induced in the albino form of sterlet Acipenser ruthenus
by activation of eggs with UV‐irradiated bester (Huso huso x Acipenser ruthenus) …

Mitotic gynogenesis results in the production of fully homozygous individuals in a single
generation. Since inbred fish were found to exhibit an increased frequency of body …

The application of cold shock to inhibit the extrusion of the second polar body in fertilized
eggs is one of the main methods to induce triploid in diploid fish. In this study, we originally …

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 …

Doubled haploid gynogens are individuals whose genetic material consists of two identical
maternal chromosome sets and who lack paternal genetic contributions. These individuals …
