    Chordate. Class Chondrichthyes. Order Carcharhiniformes. Family Carcharhinidae. Genus Carcharhinus. A group of about 50 hybrids between Australian blacktip shark and the larger common blacktip shark was found by Australia's East Coast in 2012.

  3. Hypervalent molecule - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_molecule

    Using the language of orbital hybridization, the bonds of molecules like PF 5 and SF 6 were said to be constructed from sp 3 d n orbitals on the central atom. Langmuir, on the other hand, upheld the dominance of the octet rule and preferred the use of ionic bonds to account for hypervalence without violating the rule (e.g. " SF 2+

  4. Isovalent hybridization - Wikipedia

    en.wikipedia.org/wiki/Isovalent_hybridization

    In chemistry, isovalent or second order hybridization is an extension of orbital hybridization, the mixing of atomic orbitals into hybrid orbitals which can form chemical bonds, to include fractional numbers of atomic orbitals of each type (s, p, d). It allows for a quantitative depiction of bond formation when the molecular geometry deviates ...

  5. DNA–DNA hybridization - Wikipedia

    en.wikipedia.org/wiki/DNA–DNA_hybridization

    In genomics, DNA–DNA hybridization is a molecular biology technique that measures the degree of genetic similarity between DNA sequences. It is used to determine the genetic distance between two organisms and has been used extensively in phylogeny and taxonomy .

  6. Nucleic acid hybridization - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_hybridization

    Fluorescence in situ hybridization (FISH) is a laboratory method used to detect and locate a DNA sequence, often on a particular chromosome. [4]In the 1960s, researchers Joseph Gall and Mary Lou Pardue found that molecular hybridization could be used to identify the position of DNA sequences in situ (i.e., in their natural positions within a chromosome).

  7. Cytogenetics - Wikipedia

    en.wikipedia.org/wiki/Cytogenetics

    A metaphase cell positive for the BCR/ABL rearrangement using FISH. Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis. [1]

  8. Hybrid speciation - Wikipedia

    en.wikipedia.org/wiki/Hybrid_speciation

    Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare.

  9. Hybridization assay - Wikipedia

    en.wikipedia.org/wiki/Hybridization_assay

    Despite hybridization-ligation assay's robustness, sensitivity and added specificity for the 3'-end of the oligonculeotide analyte, the hybridization-ligation assay is not specific for the 5' end of the analyte. The DLA is intended to quantify the full-length, parent oligonucleotide compound only, with both intact 5' and 3' ends.
