Polyploid plants are plants that have more than two sets of chromosomes in their cells. This can occur through various mechanisms, such as the duplication of the entire genome (autopolyploidy) or the merging of two different genomes (allopolyploidy). Polyploid plants often exhibit unique characteristics compared to their diploid counterparts, including larger cell sizes, altered gene expression patterns, and increased genetic diversity. Researchers study polyploid plants to understand the genetic and physiological consequences of polyploidy, as well as to explore their possible applications in agriculture, horticulture, and ecology.
