  2. List of organisms by chromosome count - Wikipedia

    en.wikipedia.org/wiki/List_of_organisms_by...

    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.

  3. Ploidy - Wikipedia

    en.wikipedia.org/wiki/Ploidy

    The chromosomes in each pair, one of which comes from the sperm and one from the egg, are said to be homologous. Cells and organisms with pairs of homologous chromosomes are called diploid. For example, most animals are diploid and produce haploid gametes.

  4. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    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 ...

    Human chromosomes, each of which contains an incomplete list of genes located on that chromosome, are as follows: Chromosome 1; Chromosome 2; Chromosome 3;

  6. List of Y-chromosome haplogroups in populations of the world

    The following articles are lists of human Y-chromosome DNA haplogroups found in populations around the world. Y-DNA haplogroups by ethnic group; Y-DNA haplogroups in populations of Europe; Y-DNA haplogroups in populations of the Caucasus; Y-DNA haplogroups in populations of the Near East; Y-DNA haplogroups in populations of North Africa

  7. Karyotype - Wikipedia

    en.wikipedia.org/wiki/Karyotype

    Chromosomes display a banded pattern when treated with some stains. Bands are alternating light and dark stripes that appear along the lengths of chromosomes. Unique banding patterns are used to identify chromosomes and to diagnose chromosomal aberrations, including chromosome breakage, loss, duplication, translocation or inverted segments.

  9. Genomic organization - Wikipedia

    en.wikipedia.org/wiki/Genomic_organization

    Genome sizes and corresponding composition of six major model organisms as pie charts. The increase in genome size correlates with the vast expansion of noncoding (i.e., intronic, intergenic, and interspersed repeat sequences) and repeat DNA (e.g., satellite, LINEs, short interspersed nuclear element (SINEs), DNA (Alu sequence), in red) sequences in more complex multicellular organisms.
