  2. Paternal mtDNA transmission - Wikipedia

    en.wikipedia.org/wiki/Paternal_mtDNA_transmission

    [2] [3] [4] In testing 172 sheep, "The Mitochondrial DNA from three lambs in two half-sib families were found to show paternal inheritance." [5] An instance of paternal leakage resulted in a study on chickens. [6] There has been evidences that paternal leakage is an integral part of mitochondrial inheritance of Drosophila simulans. [7]

  3. Mitochondrial Eve - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_Eve

    Branches are identified by one or more unique markers which give a mitochondrial "DNA signature" or "haplotype" (e.g. the CRS is a haplotype). Each marker is a DNA base-pair that has resulted from an SNP mutation. Scientists sort mitochondrial DNA results into more or less related groups, with more or less recent common ancestors.

  4. Mitochondrial DNA - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_DNA

    Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. [3] Human mitochondrial DNA was the first significant part of the human genome to be sequenced. [4]

  5. Biparental inheritance - Wikipedia

    en.wikipedia.org/wiki/Biparental_inheritance

    Sexual reproduction, where offspring result from the fusion of gametes from two parents, is the most common form of biparental inheritance. While less common, cases of biparental inheritance in extranuclear genes have been documented, such as biparental inheritance of mitochondrial DNA, or chloroplast DNA in plants. [1]

  6. Human mitochondrial genetics - Wikipedia

    en.wikipedia.org/wiki/Human_mitochondrial_genetics

    In humans, mitochondrial DNA (mtDNA) forms closed circular molecules that contain 16,569 [4] [5] DNA base pairs, [6] with each such molecule normally containing a full set of the mitochondrial genes. Each human mitochondrion contains, on average, approximately 5 such mtDNA molecules, with the quantity ranging between 1 and 15. [ 6 ]

  7. Heteroplasmy - Wikipedia

    en.wikipedia.org/wiki/Heteroplasmy

    [1] At birth, all copies of mitochondrial DNA are thought to be identical in most humans. [2] Microheteroplasmy is mutations of up to about 2−5% of mitochondrial genomes, and is present in most adults. This refers to hundreds of independent mutations in one organism, with each mutation found in about 1–2% of all mitochondrial genomes. [3]

  8. Genealogical DNA test - Wikipedia

    en.wikipedia.org/wiki/Genealogical_DNA_test

    Mitochondrial DNA usually has 16,569 base pairs (the number can vary slightly depending on addition or deletion mutations) [24] and is much smaller than the human genome DNA which has 3.2 billion base pairs. Mitochondrial DNA is transmitted from mother to child, as it is contained in the egg cell.

  9. Nuclear mitochondrial DNA segment - Wikipedia

    en.wikipedia.org/wiki/Nuclear_mitochondrial_DNA...

    NUMT insertion into the nuclear genome and its persistence in the nuclear genome is initiated by the physical delivery of mitochondrial DNA to the nucleus. [5] This step follows by the mtDNA integration into the genome through a non-homologous end joining mechanism during the double-strand break (DSB) repair process as envisioned by studying Saccharomyces cerevisiae, [13] [29] and terminates ...
