Such biased exchanges during chromosome recombination has been reported in other allopolyploids, and is thought to be connected to subgenome dominance. Many of cultivated plants are polyploids created by selective breeding, and are usually unable to interbreed with their diploid ancestors. Perle MA, Stein CK. Gene expression is known to be suppressed by proximity to transposable elements (TEs)18,19, and the genome of F. vesca maintains relatively low-TE content5. Strawberry varieties all exhibit their own polyploidy, which means the number of times their unique chromosomes are duplicated. The basic chromosome number in kiwi (Actinidia deliciosa) is 29. The X and Y chromosomes are known as sex chromosomes, while the other 44 human . The strawberry of commerce is octoploid (2n=8=56; seven chromosome sets and eight chromosomes per set, 56 total), meaning that each cell contains remnants of four separate ancestral diploid subgenomes that underlie strawberrys form and function. http://www.newton.dep.anl.gov/askasci/m e00596.htm, http://www.mpsaz.org/pakupfer/49docs/08 -straw.pdf. At the time it represented the 12th plant genome sequenced, and the first to be sequenced and assembled using solely short-read technology. There are more than 60 species of kiwifruit known a majority of kiwifruits are diploid with 2x=58 number of chromosomes. The genomes of these two octoploid species contain the genetic artifacts of interspecies hybridization ferried forward likely because of the fitness of the resulting natural hybrid. Generally, that is not the case, some plants have more chromosomes than animals while in some other there are less chromosomes than animals possess. This species results from the natural crossing of, Also known as the musk strawberry. Hirakawa, H. et al. 54, 221228 (1967).

The octoploid genome sequence will solve these deficits via the capacity to integrate QTL analysis with octoploid genomics. The 23rd pair, the sex chromosomes, differ between males and females. However, through human breeding, strawberries are capable of having many different chromosomal combinations by variety. 10, 81 (2010). Ville bananer er diploide med fr, mens triploide bananer er frfrie frukter. Raw RNAseq octoploid short reads, previously limited to low-resolution de novo assembly analysis, can be reassembled based on the octoploid reference to enormously enhance the level of resolution. Genetics 16, 422454 (1931). In the 1 million years since the chance formation of the hybrid octoploid genome, vestigial portions of the non-F. vesca subgenomes were eventually supplanted by F. vesca sequences8.
