партеногенез

Тезаурус:

1. Here we show that parthenogenesis - associated bacteria from parasitoid Hymenoptera also fall into this bacterial group, having up to 99% sequence similarity to some incompatibility microorganisms.
2. Thus aphid parthenogenesis shows an unfertilized ovum producing a maturing organism with no prior interaction with a male element; again, so-called graft hybrids and the effects of pollen on non-germinal tissue in a female plant both show impressionability without fertilization and maturation; while sporting and reversion in asexual plant buds show variation without fertilization or maturation.
3. Incompatibility bacteria act by interfering with paternal chromosome incorporation in fertilized eggs, whereas parthenogenesis bacteria prevent segregation of chromosomes in unfertilized eggs.
4. It seems that parthenogenesis may establish itself because of its twofold immediate advantage, but that parthenogenetic populations are ultimately eliminated, probably because they cannot evolve rapidly enough to meet changing circumstances.
5. Molecular identification of microorganisms associated with parthenogenesis
6. Both incompatibility and parthenogenesis microorganisms alter host chromosome behaviour during early mitotic divisions of the egg.
7. CYTOPLASMICALLY inherited microorganisms are widespread in insects and have been implicated as causes of female parthenogenesis (females developing from unfertilized eggs) and cytoplasmic incompatibility.
8. Cloning, parthenogenesis (development of the embryo without sperm), and even the creation of cybernetic organisms may eventually be perfected.
9. In this gall the leaf form lays a number of eggs by parthenogenesis (self-propagation) which, usually in the autumn, hatch as root forms.
10. Parthenogenesis, or something, though neither of us was exactly virginal.
11. The root form has the ability to reproduce itself by parthenogenesis several times throughout the year for a few years without passing into another form.
12. Women who I had attacked for bringing up boy children wanted to know if it had been an immaculate conception or simply parthenogenesis, and what was I going to do with it if it were a boy?
13. Perhaps the strongest is that there are species in which some females reproduce sexually, and others by parthenogenesis: if there was not a short-term advantage to sex, the parthenogenetic females would long ago have replaced the sexual ones.
