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 .

Walter Stanborough Sutton (April 5, 1877 – November 10, 1916) was an American geneticist and biologist whose most significant contribution to present-day biology was his theory that the Mendelian laws of inheritance could be applied to chromosomes at the cellular level of living organisms. This is now known as the Boveri–Sutton chromosome ...

It consists of 22 autosomes plus one copy of the X chromosome and one copy of the Y chromosome. It contains approximately 3.1 billion base pairs (3.1 Gb or 3.1 x 10 9 bp). [ 6 ] This represents the size of a composite genome based on data from multiple individuals but it is a good indication of the typical amount of DNA in a haploid set of ...
The 23 human chromosome territories during prometaphase in fibroblast cells In cell biology , chromosome territories are regions of the nucleus preferentially occupied by particular chromosomes . Interphase chromosomes are long DNA strands that are extensively folded, and are often described as appearing like a bowl of spaghetti .
Polymorphism is a general concept in biology where more than one version of a trait is present in a population. In some cases of differing counts, the difference in chromosome counts is the result of a single chromosome undergoing fission, where it splits into two smaller chromosomes, or two undergoing fusion, where two chromosomes join to form ...
An important aspect of the formation of the parent offspring is the chromosome, which is a structure of DNA which contains many genes. [ 1 ] To focus more on the offspring and how it results in the formation of the f1 generation, is an inheritance called sex linkage , [ 1 ] which is a gene located on the sex chromosome , and patterns of this ...
