Question: Most sexually reproducing organisms are diploid, with paired chromosomes, but doubling of their chromosome number may occur due to errors in cytokinesis. This can occur early in development to produce an autopolyploid or partly autopolyploid organism, or during normal processes of cellular differentiation to produce some cell types that are polyploid (endopolyploidy), or during gamete formation. An allopolyploid plant may result from a hybridisation event between two different species. Both autopolyploid and allopolyploid plants can often reproduce normally, but may be unable to cross-breed successfully with the parent population because there is a mismatch in chromosome numbers. These plants that are reproductively isolated from the parent species but live within the same geographical area, may be sufficiently successful to form a new species. Some otherwise sterile plant polyploids can still reproduce vegetatively or by seed apomixis, forming clonal populations of identical individuals. Durum wheat is a fertile tetraploid allopolyploid, while bread wheat is a fertile hexaploid. The commercial banana is an example of a sterile, seedless triploid hybrid. Common dandelion is a triploid that produces viable seeds by apomictic seed.
Try to answer this question if possible: What happens to these new plants if they are able to reproduce?
Answer: form a new species
Question: The island's unique social and economic organisation has evolved over the years, but is based on the principles set out by William Glass in 1817 when he established a settlement based on equality. All Tristan families are farmers, owning their own stock and/or fishing. All land is communally owned. All households have plots of land at The Patches on which they grow potatoes. Livestock numbers are strictly controlled to conserve pasture and to prevent better-off families from accumulating wealth. Unless it votes for a change in its law, no outsiders are allowed to buy land or settle on Tristan; theoretically the whole island would have to be put up for sale. All people including children and pensioners are involved in farming, while adults additionally have salaried jobs working either for the Government, or, a small number in domestic service, and many of the men are involved in the fishing industry, going to sea in good weather. The nominal fishing season lasts 90 days; however during the 2013 fishing season 1 July through 30 September there were only 10 days suitable for fishing.

Question: On 14 September 2009, U.S. Special Forces killed two men and wounded and captured two others near the Somali village of Baarawe. Witnesses claim that helicopters used for the operation launched from French-flagged warships, but that could not be confirmed. A Somali-based al-Qaida affiliated group, the Al-Shabaab, has confirmed the death of "sheik commander" Saleh Ali Saleh Nabhan along with an unspecified number of militants. Nabhan, a Kenyan, was wanted in connection with the 2002 Mombasa attacks.

Question: The impressive, costly, and centralised rites to the deities of the Roman state were vastly outnumbered in everyday life by commonplace religious observances pertaining to an individual's domestic and personal deities, the patron divinities of Rome's various neighborhoods and communities, and the often idiosyncratic blends of official, unofficial, local and personal cults that characterised lawful Roman religion. In this spirit, a provincial Roman citizen who made the long journey from Bordeaux to Italy to consult the Sibyl at Tibur did not neglect his devotion to his own goddess from home:
