  2. Chromosome 22 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_22

    Chromosome 22 is one of the 23 pairs of chromosomes in human cells. Humans normally have two copies of chromosome 22 in each cell. Humans normally have two copies of chromosome 22 in each cell. Chromosome 22 is the second smallest human chromosome, spanning about 51 million DNA base pairs and representing between 1.5 and 2% of the total DNA in ...

  3. Chromosome 1 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_1

    Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes , which are the non- sex chromosomes . Chromosome 1 spans about 249 million nucleotide base pairs , which are the basic units of information for DNA . [ 4 ]

  4. Autosome - Wikipedia

    en.wikipedia.org/wiki/Autosome

    Karyotype of human chromosomes ; Female (XX) Male (XY) There are two copies of each autosome (chromosomes 122) in both females and males. The sex chromosomes are different: There are two copies of the X-chromosome in females, but males have a single X-chromosome and a Y-chromosome.

  5. Chromosome - Wikipedia

    en.wikipedia.org/wiki/Chromosome

    Certain genetic traits are linked to a person's sex and are passed on through the sex chromosomes. The autosomes contain the rest of the genetic hereditary information. All act in the same way during cell division. Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell.

  6. 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 ...

  7. Homologous chromosome - Wikipedia

    en.wikipedia.org/wiki/Homologous_chromosome

    So, humans have two sets of 23 chromosomes in each cell that contains a nucleus. One set of 23 chromosomes (n) is from the mother (22 autosomes, 1 sex chromosome (X only)) and one set of 23 chromosomes (n) is from the father (22 autosomes, 1 sex chromosome (X or Y)). Ultimately, this means that humans are diploid (2n) organisms. [2]

  8. Aneuploidy - Wikipedia

    en.wikipedia.org/wiki/Aneuploidy

    The first 22 pairs of chromosomes (called autosomes) are numbered from 1 to 22, from largest to smallest. The 23rd pair of chromosomes are the sex chromosomes . Typical females have two X chromosomes , while typical males have one X chromosome and one Y chromosome .

  9. Karyotype - Wikipedia

    [1] [2] Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities.
