  2. Right bundle branch block - Wikipedia

    en.wikipedia.org/wiki/Right_bundle_branch_block

    A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.

  3. Non-Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Non-Mendelian_inheritance

    An example in dog coat genetics is the homozygosity with the allele "e e" on the Extension-locus making it impossible to produce any other pigment than pheomelanin. Although the allele "e" is a recessive allele on the extension-locus itself, the presence of two copies leverages the dominance of other coat colour genes.

  4. Intraventricular block - Wikipedia

    en.wikipedia.org/wiki/Intraventricular_block

    Intraventricular conduction delay seen in precordial/chest leads with QRS duration 100 ms. An EKG of a 25-year-old male. Intraventricular conduction delays (IVCD) are conduction disorders seen in intraventricular propagation of supraventricular impulses resulting in changes in the QRS complex duration or morphology, or both.

  5. Bundle branch block - Wikipedia

    en.wikipedia.org/wiki/Bundle_branch_block

    A right bundle branch block typically causes prolongation of the last part of the QRS complex and may shift the heart's electrical axis slightly to the right. The ECG will show a terminal R wave in lead V1 and a slurred S wave in lead I. Left bundle branch block widens the entire QRS, and in most cases shifts the heart's electrical axis to the ...

  6. Mendelian traits in humans - Wikipedia

    en.wikipedia.org/wiki/Mendelian_traits_in_humans

    Therefore no trait is purely Mendelian, but many traits are almost entirely Mendelian, including canonical examples, such as those listed below. Purely Mendelian traits are a minority of all traits, since most phenotypic traits exhibit incomplete dominance, codominance, and contributions from many genes.

    With 1,838 yards, the seven-year veteran has to average 133.5 yards in those final two games to seize the all-time mark. Barkley has topped that number in six of his 15 games this season.

  8. Simple Mendelian genetics in humans - Wikipedia

    en.wikipedia.org/wiki/Simple_Mendelian_genetics...

    Very few phenotypes are purely Mendelian traits. Common violations of the Mendelian model include incomplete dominance, codominance, genetic linkage, environmental effects, and quantitative contributions from a number of genes (see: gene interactions, polygenic inheritance, oligogenic inheritance). [1] [2]

  9. Dominance (genetics) - Wikipedia

    en.wikipedia.org/wiki/Dominance_(genetics)

    Co-dominance, where allelic products co-exist in the phenotype, is different from incomplete dominance, where the quantitative interaction of allele products produces an intermediate phenotype. For example, in co-dominance, a red homozygous flower and a white homozygous flower will produce offspring that have red and white spots.
