Other names for this species: Fraises des Bois, Wild (European) Strawberry, European Strawberry, Woodland Strawberry, and Alpine Strawberry (the latter is the most common type in cultivation, which usually is nearly always everbearing, and produces few runners). The National Human Genome Research Institute says that strawberries have seven unique chromosomes. Aberrant crossover between strawberrys highly similar subgenomes during meiosis led to unequal chromosomal exchanges and gene conversion, as has been reported in coffee20. Appl. A . Ok. The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. 6, 32953313 (2014). Why? The plant is native to mainland China and Taiwan and is also grown commercially in New Zealand and California. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome. Antall kromosomer varierer forskjellig og navngis deretter, for eksempel Aneuploidy, Paleo polyploidy og neo polyploidy. The octoploid genome sequence will solve these deficits via the capacity to integrate QTL analysis with octoploid genomics.
