It shows dark and white regions as seen on G banding. Each row is vertically aligned at centromere level. The karyogram shows: - 22 homologous autosomal chromosome pairs - Both the female (XX) and male (XY) versions of the two sex chromosomes. For printing this image as a poster, the suggested size is approximately 47 x 79 cm.

English: Statistics for the human chromosomes, based on the Sanger Institute's human genome information in the Vertebrate Genome Annotation (VEGA) database accessed 2012-03-05. The total number of genes is an estimate as it is in part based on gene predictions.
[4] [3] The human Y chromosome, consisting of 62,460,029 base pairs from a different cell line and found in all males, was sequenced completely in January 2022. [5] The current version of the standard reference genome is called GRCh38.p14 (July 2023). It consists of 22 autosomes plus one copy of the X chromosome and one copy of the Y chromosome.
A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle , and results in a photomicrographic (or simply ...
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 .
It shows dark and white regions as seen on G banding. Each row is vertically aligned at centromere level. It shows 22 homologous autosomal chromosome pairs, both the female (XX) and male (XY) versions of the two sex chromosomes, as well as the mitochondrial genome (at bottom left).
