What Animal Has The Most Amount Of Chromosomes

The list of organisms past chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype,^{[2] [3] [4]} and can exist found past looking at the chromosomes through a microscope. Attention is paid to their length, the position of the centromeres, banding blueprint, whatsoever differences between the sex chromosomes, and any other concrete characteristics.^[v] The preparation and study of karyotypes is part of cytogenetics.

The sex-determination arrangement used by this species and most other bryophytes is called UV. Spores tin can carry either the U chromosome, which results in female gametophytes, or the 5 chromosome, which results in males. The chromosome number n = ix is the bones number in many species of Marchantiales. In some species of Marchantiales, plants with various ploidy levels (having 18 or 27 chromosomes) were reported, but this is rare in nature. ^[15] Thale cress
