diploid
Biology (of cells or organisms) having pairs of homologous chromosomes so that twice the haploid number is present diploid [′di‚plȯid] (crystallography) A crystal form in the isometric system having 24 similar quadrilateral faces arranged in pairs. (genetics) Having two complete chromosome pairs in a nucleus (2N). Diploid an organism whose cells have a double (diploid; 2n) set of chromosomes, representing a single (haploid; n) set of paired homologous chromosomes. For example, man has 23 pairs of chromosomes (n = 23’,2n = 46), and an onion has eight pairs of chromosomes (n = 8; 2n = 16). The transition from the diploid state (diplophase) to the haploid (haplo-phase) is accomplished by the first meiotic division, as a result of which the sex cells, or gametes, are formed. When the gametes fuse, the diploid number of chromosomes is restored. Want to thank TFD for its existence?

No references found | The scientists' exhaustive survey of published phylogenetic and genomic data also shows that plant lineages starting with a polyploid ancestor appear to be no more successful at spawning species than diploid plants, which have two sets of chromosomes. Manton's extensive survey demonstrated that most ferns had extraordinarily high chromosome numbers and that often what appeared to be polymorphic species were actually reticulate complexes of diploid species and their allopolyploid derivatives.
