  2. Non-Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Non-Mendelian_inheritance

    In cases of intermediate inheritance due to incomplete dominance, the principle of dominance discovered by Mendel does not apply.Nevertheless, the principle of uniformity works, as all offspring in the F 1-generation have the same genotype and same phenotype.

  3. Dominance (genetics) - Wikipedia

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

    Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.

  4. 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]

  5. 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.

  6. Genotype - Wikipedia

    en.wikipedia.org/wiki/Genotype

    Codominance refers to traits in which both alleles are expressed in the offspring in approximately equal amounts. [20] A classic example is the ABO blood group system in humans, where both the A and B alleles are expressed when they are present. Individuals with the AB genotype have both A and B proteins expressed on their red blood cells. [20 ...

  9. Sickle cell trait - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_trait

    An individual with the sickle cell trait shows incomplete dominance when the shape of the red blood cell is considered. This is because the sickling happens only at low oxygen concentrations. With regards to the actual concentration of hemoglobin in the circulating cells, the alleles demonstrate co-dominance as both 'normal' and mutant forms co ...
