Endosymbiotic relationships -- in which one organism lives within another -- are striking examples of mutualism, and can often significantly shape the biology of the participant species. In new ...

Researchers meticulously examined the gametogenesis of budding yeast, a process involving meiosis and spore formation, using live imaging techniques. Their findings revealed that during sporulation, ...

Whereas most prokaryotes rely on binary fission for propagation, many species use alternative mechanisms, which include multiple offspring formation and budding, to reproduce. In some bacterial ...

PROF. COULTER gives a luminous sketch of the probable history of sexual reproduction in plants. He deals with the origin of pairing gametes from spores, with the differentiation of (1) eggs and sperms ...
