  2. Serial homology - Wikipedia

    en.wikipedia.org/wiki/Serial_homology

    Serial homology is a special type of homology, defined by Owen as "representative or repetitive relation in the segments of the same organism." [ 1 ] Ernst Haeckel preferred the term "homotypy" for the same phenomenon.

  3. Metamerism (biology) - Wikipedia

    en.wikipedia.org/wiki/Metamerism_(biology)

    Earthworms are a classic example of biological homonymous metamery – the property of repeating body segments with distinct regions. In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. [1]

  4. Homology (biology) - Wikipedia

    en.wikipedia.org/wiki/Homology_(biology)

    In biology, homology is similarity in anatomical structures or genes between organisms of different taxa due to shared ancestry, regardless of current functional differences. Evolutionary biology explains homologous structures as retained heredity from a common ancestor after having been subjected to adaptive modifications for different ...

  5. Deep homology - Wikipedia

    en.wikipedia.org/wiki/Deep_homology

    Whereas ordinary homology is seen in the pattern of structures such as limb bones of mammals that are evidently related, deep homology can apply to groups of animals that have quite dissimilar anatomy: vertebrates (with endoskeletons made of bone and cartilage) and arthropods (with exoskeletons made of chitin) nevertheless have limbs that are constructed using similar recipes or "algorithms".

  6. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...

  7. Homology - Wikipedia

    en.wikipedia.org/wiki/Homology

    Homology (anthropology), analogy between human beliefs, practices or artifacts owing to genetic or historical connections; Homology (psychology), behavioral characteristics that have common origins in either evolution or development

  8. PTPN6 - Wikipedia

    en.wikipedia.org/wiki/PTPN6

    Tyrosine-protein phosphatase non-receptor type 6, also known as Src homology region 2 domain-containing phosphatase-1 (SHP-1), is an enzyme that in humans is encoded by the PTPN6 gene. [ 5 ] Function

  9. DNA shuffling - Wikipedia

    en.wikipedia.org/wiki/DNA_shuffling

    Nonhomologous random recombination differs from molecular breeding as homology of the ligated sequences is not necessary which is an advantage. [1] However , because this process recombines the fragments randomly it is probable that a large fraction of the recombined DNA sequences will not have the desired characteristics which is a ...
