Q. "How is the that complicated creatures deserve to have the same number or less chromosomes then a very straightforward organism?"i.e. The "C worth enigma" ... Http://en.wikipedia.org/wiki/C-value_enigmaPossibly varieties which room older, or which have actually a brief life-cycle, have actually accumulated an ext junk DNA ...

Chromosomes deserve to split, or fuse, leading to bigger or smaller sized chromosomes. Chimps & Apes have actually 48 chromosomes, while human beings only have 46 because of a 2a/2b fusion. However, us may have a larger mind than a chimp, however otherwise it would be tough to speak whether us are much more or less developed than them.Anyway, you might look at:Chromosome NumberNumber the GenesNumber of basic Pairs or NucleotidesNumber of base Pairs per geneTo a huge extent, the number of genes and also base pairs does rise with the more complicated organisms. However, as RD noted, the "Junk DNA" can likewise be quite variable, or in part cases, genes can be repeated.Here is an interesting Wikipedia graph on Genome Size. To some extent, the complexity of the organism adheres to the genome size, but for example Flowering plants covers a very wide selection of genome sizes.In the center of this page, over there is a nice chart on the variety of genes and base pairs for a few select organisms. It is interesting that the gene density for Mammals is reasonably low. Not necessarily more facility genes, but rather an ext non-coding DNA.
