  2. Pedigree chart - Wikipedia

    en.wikipedia.org/wiki/Pedigree_chart

    Example of a pedigree chart using Ahnentafel numbering. A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes [jargon] of a particular gene or organism and its ancestors from one generation to the next, [1] [2] [3] [unreliable source?] most commonly humans, show dogs, and race horses.

  3. Non-Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Non-Mendelian_inheritance

    Extranuclear inheritance (also known as cytoplasmic inheritance) is a form of non-Mendelian inheritance also first discovered by Carl Correns in 1908. [9] While working with Mirabilis jalapa, Correns observed that leaf colour was dependent only on the genotype of the maternal parent.

  4. Gene mapping - Wikipedia

    en.wikipedia.org/wiki/Gene_mapping

    There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.

  5. Extranuclear inheritance - Wikipedia

    en.wikipedia.org/wiki/Extranuclear_inheritance

    Extranuclear inheritance or cytoplasmic inheritance is the transmission of genes that occur outside the nucleus. It is found in most eukaryotes and is commonly known to occur in cytoplasmic organelles such as mitochondria and chloroplasts or from cellular parasites like viruses or bacteria .

  7. Quantitative genetics - Wikipedia

    en.wikipedia.org/wiki/Quantitative_genetics

    Illustrative pedigree. Pedigrees are diagrams of familial connections between individuals and their ancestors, and possibly between other members of the group that share genetical inheritance with them. They are relationship maps. A pedigree can be analyzed, therefore, to reveal coefficients of inbreeding and co-ancestry.

  8. Paternal mtDNA transmission - Wikipedia

    en.wikipedia.org/wiki/Paternal_mtDNA_transmission

    In genetics, paternal mtDNA transmission and paternal mtDNA inheritance refer to the incidence of mitochondrial DNA (mtDNA) being passed from a father to his offspring. . Paternal mtDNA inheritance is observed in a small proportion of species; in general, mtDNA is passed unchanged from a mother to her offspring, [1] making it an example of non-Mendelian inh

    Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
