autopolyploid การใช้

• This fact can be exploited in a laboratory setting by using colchicine to inhibit chromosome segregation during meiosis, creating synthetic autopolyploid plants.
• He was able to establish the plant in the field, and after 39 years of field trials was able to show that the autopolyploid was not as successful as its diploid parent in an unchanging environment.
• 'Heterosis without hybridity'effects on plant size have been demonstrated in genetically isogenic F1 triploid ( autopolyploid ) plants, where paternal genome excess F1 triploids display positive heterosis, whereas maternal genome excess F1s display negative heterosis effects.
• As time passes after a genome duplication event, many genes will change function as a result of either change in duplicate gene function for both allo-and autopolyploid species, or there will be changes in gene expression caused by genomic rearrangements induced by genome duplication in allopolyploids.
• :" In contrast, the second mode, sympatric speciation, is species divergence without geographic isolation, and its identification is typically controversial, since even a small amount of gene flow may be sufficient to homogenize a potentially diverging species . [ 137 ] [ 138 ] Generally, models of sympatric speciation in animals require the evolution of stable polymorphisms associated with non-random assortative mating, in order for reproductive isolation to evolve . [ 139 ] However, a common mechanism of sympatric speciation in plants appears to the the formation of polyploid species and can involve either a single plant doubling its numbers of chromosomes ( an autopolyploid such as cabbage ), [ 140 ] or two related plants cross-breeding to form an allopolyploid such as wheat .
