The production of two heterozygous and one homozygous clones of the Israeli Dor-70 line of common carp (Cyprinus carpio L.) was tested using DNA fingerprinting (DFP) and mixed leukocyte reaction (MLR) analysis. The clones were obtained in large-scale production from mitotic gynogenetic females and males (sex-inversed). MLR analysis was used to examine major histocompatibility complex (MHC) anti...

■ Abstract Most metazoans engage in recombination every generation. In theory this is associated with considerable cost, such as the production of males, so that asexual organisms, which do not pay this cost, should be able to invade populations of sexuals. Some asexuals depend on sperm of sexual males to trigger embryogenesis, a reproductive mode called gynogenesis. The genetic information of ...

Vuralia turcica is an endemic plant species with a polycarpellary gynoecium and has the ability to survive in salt stress. However, maintenance of this currently challenging because climatic changes plant’s habitat, intensive agricultural purposes, grazing, like. Gynogenesis promising method for micropropagation useful technic genetic engineering. The objective study was analyze gynogenesis V. ...

In so-called unisexual teleost fishes, a broad spectrum of evolutionary stages with varying amounts of sexual elements has evolved. These range from pure sperm-dependent parthenogenesis (gynogenesis) without or with different amounts of paternal leakage to hybridogenesis with hemiclonal diploid gametogenesis or genome elimination followed by meiosis (meiotic hybridogenesis). All of these phenom...
