  2. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    The mitochondrial genome is shown to scale at bottom left. The human genome is a complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome ...

    One is from mother, one is from father. in human male karyogram. Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 3 spans more than 198 million base pairs (the building material of DNA) and represents about 6.5 percent of the total DNA in cells.

    The International System for Human Cytogenomic Nomenclature (ISCN; previously the International System for Human Cytogenetic Nomenclature) is an international standard for human chromosome nomenclature, which includes band names, symbols, and abbreviated terms used in the description of human chromosome and chromosome abnormalities.

  6. Genealogical DNA test - Wikipedia

    en.wikipedia.org/wiki/Genealogical_DNA_test

    The Y-chromosome is one of the 23rd pair of human chromosomes. Only males have a Y-chromosome, because women have two X chromosomes in their 23rd pair. A man's patrilineal ancestry, or male-line ancestry, can be traced using the DNA on his Y-chromosome (Y-DNA), because the Y-chromosome is transmitted from a father to son nearly unchanged. [31]

    Chromosome 19. Human chromosome 19 pair after G-banding. One is from mother, one is from father. in human male karyogram. Chromosome 19 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 19 spans more than 61.7 million base pairs, the building material of DNA.

  8. Genetic linkage - Wikipedia

    en.wikipedia.org/wiki/Genetic_linkage

    Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.

  9. Chromosome 11 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_11

    CM000673 (FASTA) Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells. The shorter arm (p arm) is termed 11p while the longer arm (q arm ...
