NOT SIMPLE. "Most bacteria rely on binary fission for propagation. Conceptually this is a simple process; a cell just needs to grow to twice its starting size and then split in two. But, to remain viable and competitive, a bacterium must divide at the right time, in the right place, and must provide each offspring with a complete copy of its essential genetic material." https://lnkd.in/eqsJf6Q View in LinkedIn

SUDDEN EVOLUTIONARY JUMPS. "Transgressive segregation might be an important mechanism promoting sudden phenotypic changes and ecological transitions in evolution. Even if most of the variation produced is deleterious, a rare transgressive hybrid genotype could rapidly fix in a population or establish a novel lineage." http://link.springer.com/article/10.1007/s11692-012-9209-0 View in LinkedIn

TRANSGRESSIVE PHENOTYPES. "Interspecific hybridization and allopolyploidy provide the opportunity for new, transgressive characters to evolve. Transgressive characters can be observed at all levels from the transcriptome to inflorescence morphology and may arise through novel cis-trans interactions in the genome or by 'mixing and matching' of different metabolic pathways found in the parents." https://genomebiology.biomedcentral.com/articles/10.1186/gb-2013-14-6-207 View in LinkedIn

LEAKY SPECIES BARRIER. "Interspecific hybridization can generate a large range of characters in hybrids, including intermediate characters and potentially characters that fall outside the range found in the parents (transgressive characters). Hybrids usually backcross to one or both of the parents, providing gene flow between species." https://lnkd.in/dHD-ddW View in LinkedIn

METAZOAN FISSION. “A few metazoan (multicellular) species regularly undergo a body division into several units simultaneously, a process called fragmentation. Planarian fission and fragmentation generally represent direct reproduction in which each portion regenerates missing parts to become a complete new animal. Strobilation products, however, are only indirectly reproductive: proglottids are not regenerative but carry and release great numbers of eggs and die; ephyrae do not produce new polyps but mature into sexually reproducing medusae, the larvae of which become polyps.” https://lnkd.in/dkDex6F View in LinkedIn

FISSION ACROSS TAXA. “Regular transverse fission in some organisms, such as tapeworms and scyphostome polyps, is called strobilation. Commonly, this results in a chain, called a strobilus, of the fission products—the proglottids of tapeworms and the ephyrae of scyphozoan jellyfish; each proglottid or ephyra matures in turn and separates from the end of the strobilus.” https://lnkd.in/dkDex6F View in LinkedIn

ASEXUAL BINARY FISSION is where every organ is copied as the cell divides in two. Examples include bacteria and protists. “Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.” https://lnkd.in/dkDex6F View in LinkedIn
