  2. Chromosome 9 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_9

    Chromosome 9 is one of the 23 pairs of chromosomes in humans.Humans normally have two copies of this chromosome, as they normally do with all chromosomes. Chromosome 9 spans about 138 million base pairs of nucleic acids (the building blocks of DNA) and represents between 4.0 and 4.5% of the total DNA in cells.

  3. Philadelphia chromosome - Wikipedia

    en.wikipedia.org/wiki/Philadelphia_chromosome

    The chromosomal defect in the Philadelphia chromosome is a reciprocal translocation, in which parts of two chromosomes, 9 and 22, swap places. The result is that a fusion gene is created by juxtaposing the ABL1 gene on chromosome 9 (region q34) to a part of the BCR (breakpoint cluster region) gene on chromosome 22 (region q11).

  4. 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 ...

  5. 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 ...

  6. ZW sex-determination system - Wikipedia

    en.wikipedia.org/wiki/ZW_sex-determination_system

    The ZW sex-determination system is a chromosomal system that determines the sex of offspring in birds, some fish and crustaceans such as the giant river prawn, some insects (including butterflies and moths), the schistosome family of flatworms, and some reptiles, e.g. majority of snakes, lacertid lizards and monitors, including Komodo dragons.

  7. Second Generation Multiplex Plus - Wikipedia

    en.wikipedia.org/wiki/Second_Generation...

    An SGM Plus profile retrieved from a DNA database would just list the allele values: [4] 15,18; 6,9; 11,13; 22,22; 31,32.2; 14,17; 17,20; 11,12; 13,16.3; 15,16; XY Each value is the number of tandem repeats within the allele. A non-standard repeat is designated by the number of complete repeat units and the number of base pairs of the partial ...

  8. Monosomy 9p - Wikipedia

    en.wikipedia.org/wiki/Monosomy_9p

    Monosomy 9p (also known as Alfi's Syndrome, 9p Minus or simply 9P-) is a rare chromosomal disorder in which some DNA is missing or has been deleted on the short arm region, "p", of one copy of chromosome 9 (9p22.2-p23). [1] [2] This deletion either happens de novo or as a result of a parent having the chromosome abnormality. [3]

  9. Small supernumerary marker chromosome - Wikipedia

    en.wikipedia.org/wiki/Small_supernumerary_marker...

    This derivative chromosome contains an exchange, termed t(11;22), or der22 (22) t (11;22), between the q arm of chromosome 22 around band 11.2 and the q arm of chromosome 11 around band 21. In ~10% of cases, carriers of this chromosome have a child with ES, with male and female carriers having 0.7% and 3.4%, respectively, chances of parenting ...
