Biology:List of organisms by chromosome count

From HandWiki
Short description: None

The list of organisms by 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,[1][2][3] and can be found by looking at the chromosomes through a microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.[4] The preparation and study of karyotypes is part of cytogenetics.

1 Jack jumper ant

10 Marchantia polymorpha 09 9


Moos 5772.jpg Marchantia polymorpha male karyotype.jpg Typically haploid with dominant gametophyte stage. 8 autosomes and 1 allosome (sex chromosome). The sex-determination system used by this species and most other bryophytes is called UV. Spores can carry either the U chromosome, which results in female gametophytes, or the V chromosome, which results in males. The chromosome number n = 9 is the basic 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. [14]
