LACK OF MAMMALIAN PARTHENOGENESIS. "Mammals are believed to be completely unable to reproduce via parthenogenesis because of a number of developmental and genetic constraints." http://www.sciencedirect.com/science/article/pii/S0960982215007824 View in LinkedIn

SO ENDS this first weekend Fragment from Nature exploring how plants recognize kin versus non-kin. As we become increasingly urbanized and disconnected from nature, our views of the natural world become increasingly distanced, and plants assume the identity of plastic cut-outs, bearing little or no sense of being. On the contrary, increasingly science is illustrating the intensely related and feeling nature of plants. The salad breathes. View in LinkedIn

INTERESTING QUESTION. "Parthenogenesis — the ability to produce offspring from unfertilized eggs — is widespread among invertebrates and now increasingly found in normally sexual vertebrates. Are these cases reproductive errors or could they be a first step in the emergence of new parthenogenetic lineages?" https://lnkd.in/gvZ8CFZ View in LinkedIn

"VOLATILE CUES from close kin may be more easily perceived by kin or may provide more reliable information about probable risk. The ability to differentially communicate based on relatedness makes possible a wide variety of social behaviours for plants that have previously been thought to be solely within the repertoire of animals." http://rspb.royalsocietypublishing.org/content/280/1756/20123062.short View in LinkedIn

“ASEXUAL PARTHENOGENESIS is used by the Komodo Dragon, which can reproduce without a mate. Bees, wasps and ants which have no sex chromosomes reproduce by this method. Some reptiles and fish also utilize parthenogenesis.” https://lnkd.in/gMaYvUK View in LinkedIn

VERTEBRATE PARTHENOGENESIS. "Some vertebrate animals, such as certain reptiles, amphibians, and fish, also reproduce through parthenogenesis. Although more common in plants, parthenogenesis has been observed in animal species that were segregated by sex in terrestrial or marine zoos. Two Komodo dragons, a bonnethead shark, and a blacktip shark have produced parthenogenic young when the females have been isolated from males." https://lnkd.in/d_e3R-w View in LinkedIn

HAPLOID AND DIPLOID. "Parthenogenesis occurs in invertebrates such as water fleas, rotifers, aphids, stick insects, some ants, wasps, and bees. Bees use parthenogenesis to produce haploid males (drones) and diploid females (workers). If an egg is fertilized, a queen is produced. The queen bee controls the reproduction of the hive bees to regulate the type of bee produced." https://lnkd.in/d_e3R-w View in LinkedIn

"PARTHENOGENESIS is a form of asexual reproduction where an egg develops into a complete individual without being fertilized. The resulting offspring can be either haploid or diploid, depending on the process and the species." https://lnkd.in/d_e3R-w View in LinkedIn

SPECIALITY LIFESTYLE. "On the basis of their sequence similarities, we conclude that parthenogenesis bacteria and cytoplasmic incompatibility bacteria form a monophyletic group of microorganisms that 'specialize' in manipulating chromosome behaviour and reproduction of insects." http://www.nature.com/nature/journal/v361/n6407/abs/361066a0.html View in LinkedIn

REPRODUCTIVE INTERFERENCE. "Both incompatibility and parthenogenesis microorganisms alter host chromosome behaviour during early mitotic divisions of the egg. Incompatibility bacteria act by interfering with paternal chromosome incorporation in fertilized eggs, whereas parthenogenesis bacteria prevent segregation of chromosomes in unfertilized eggs. These traits are adaptive for the microorganisms." http://www.nature.com/nature/journal/v361/n6407/abs/361066a0.html View in LinkedIn
