what is autopolyploidy?how does colchicine induce polyploidy?name an autopolypioid that has succeeded as a variety?
When a cell is having more than two paired sets of homologous chromosomes, the condition is known as polyploidy. Autopolyploidy is a phenomenon where one or more extra sets of chromosomes occur due to mutation at the time of cell division.
Colchicine prevents the formation of spindle fibers during cell division. As a result there is no movement of chromatids in anaphase and they settle inside the single nucleus forming an extra set of chromosome.
Seedless watermelon is an example of polyploidy that has succeeded as a variety.
