How Many Copies Of Each Chromosome Are Found In Most Animal Cells? 4 1 2 3

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 advent of the chromosome, is known every bit the karyotype,^{[two] [iii] [4]} and can be institute by looking at the chromosomes through a microscope. Attending is paid to their length, the position of the centromeres, banding pattern, whatever differences between the sex chromosomes, and whatsoever other concrete characteristics.^[5] The preparation and written report of karyotypes is function of cytogenetics.

(Myrmecia pilosula) 2/1 2 for females, males are haploid and thus take 1; smallest number possible. Other ant species have more chromosomes.^{[half dozen] [six]} Spider mite
(Tetranychidae) 4–fourteen Spider mites (family Tetranychidae) are typically haplodiploid (males are haploid, while females are diploid)^{[seven] [seven]} Cricotopus sylvestris 4 ^[8] Oikopleura dioica half dozen ^[9] Xanthous fever mosquito
(Aedes aegypti) 6 The 2n=6 chromosome number is conserved in the unabridged family Culicidae, except in Chagasia bathana, which has 2n=eight.^{[10] [10]} Indian muntjac
(Muntiacus muntjak) vi/seven 2n = 6 for females and vii for males. The lowest diploid chromosomal number in mammals.^{[xi] [12]} Hieracium viii Fruit fly
(Drosophila melanogaster) viii 6 autosomal and 2 allosomic (sex) ^[xiii] Macrostomum lignano 8 ^[xiv] Marchantia polymorpha ix Typically haploid with dominant gametophyte stage. viii autosomes and 1 allosome (sex activity chromosome). The sexual activity-determination system used by this species and most other bryophytes is called UV. Spores tin carry either the U chromosome, which results in female gametophytes, or the V chromosome, which results in males. The chromosome number n = ix 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. ^[15] Thale cress

(Sarcoptes scabiei) 17/18 Co-ordinate to the ascertainment of embryonic cells of egg, chromosome number of the itch mite is either 17 or xviii. While the crusade for the disparate numbers is unknown, it may arise because of an XO sex determination machinery, where males (2n=17) lack the sex chromosome and therefore accept 1 less chromosome than the female (2n=18).^{[xxx] [30]} Radish
