Strawberry Plants LLC. by johny_depp_rocks Wed Dec 17, 2008 5:50 pm, Post 51, 541547 (2019). 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. Edger and colleagues identify the various subtypes and note their considerable expansion over the diploid F. vesca genome alone. In any given asexually reproducing species, the chromosome number is always the same. Again, the elucidation of the complete octoploid sequence allows scientists to begin to piece together how the dominant subgenome shaped the genome as a whole under the process of selection. In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Variasjon i antall av kromosomer er funnet i arten selv. Mol. Chromosomes come in pairs.
