divided by the ploidy level of the somatic cells: 48 chromosomes in total divided by a ploidy level of 4 equals a monoploid number of 12. hence, the monoploid number (12) and haploid number (24) are distinct in this example. however, commercial potato crops (as well as many other crop plants) are commonly propagated vegetatively (by asexual reproduction through mitosis), in which case new individuals are produced from a single parent, without the involvement of gametes and fertilization, and all the offspring are genetically identical to each other and to the parent, including in chromosome number. the parents of these vegetative clones may still be capable of producing haploid gametes in preparation for sexual reproduction, but these gametes are not used to create the vegetative offspring by this route. specific examples examples of various ploidy levels in species with x=11 speciesploidynumber of chromosomes eucalyptus spp.diploid2x = 22 banana (musa spp.)triploid3x = 33 coffea arabicatetraploid4x = 44 sequoia sempervirenshexaploid6x = 66 opuntia ficus-indicaoctoploid8x = 88 list of common organisms by chromosome count speciesnumber of chromosomesploidy number vinegar/fruit fly82 wheat14, 28 or 422, 4 or 6 crocodilian32, 34, or 422 apple34, 51, or 682, 3 or 4 human462 horse642 chicken782 gold fish100 or more2 or polyploid notes compare the etymology of tuple, from the latin for "-fold". the original text in german is as follows: "schließlich wäre es vielleicht erwünscht, wenn den bezeichnungen gametophyt und sporophyt, die sich allein nur auf pflanzen mit einfacher und mit doppelter chromosomenzahl anwenden lassen, solche zur seite gestellt würden, welche auch für das tierreich passen. ich erlaube mir zu diesem zwecke die worte haploid und diploid, bezw. haploidische und diploidische generation vorzuschlagen."
