#alopoliploid
- Allopolyploid — An organism, cell, or individual possessing more than two complete sets of chromosomes (being polyploid), resulting from the hybridization between two or more distinct species, followed by chromosome doubling. This hybrid structural phenomenon combines non-homologous genomes, being extremely widespread in the plant kingdom (for instance, in wheat or cotton), where it ensures enhanced vigor and restored fertility.
- Allopolyploidy — The state, property, or structural phenomenon consisting of the presence of more than two chromosome sets originating from distinct species following interspecific hybridization. Allopolyploidy represents a major evolutionary engine in the plant kingdom, allowing the instantaneous emergence of new, fertile species reproductively isolated from their parents, combining the genetic advantages of both ancestral lines.
- Amphidiploidy — A genetic state or a particular type of polyploidy (allopolyploidy) characterized by the presence of a complete diploid set of chromosomes derived from two different parental species following hybridization and subsequent chromosome doubling. This structural phenomenon guarantees the fertility of the hybrid, allowing normal pairing of homologous chromosomes during meiosis, and is widely used in plant genetic engineering to create new plant varieties.
