    Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.

  3. Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Mendelian_inheritance

    Mendelian inheritance (also known as Mendelism) is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and later popularized by William Bateson. [1]

  4. Simple Mendelian genetics in humans - Wikipedia

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

    Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.

  5. Gene - Wikipedia

    en.wikipedia.org/wiki/Gene

    The Mendelian gene is the classical gene of genetics and it refers to any heritable trait. This is the gene described in The Selfish Gene . [ 9 ] More thorough discussions of this version of a gene can be found in the articles Genetics and Gene-centered view of evolution .

  6. Genotype - Wikipedia

    en.wikipedia.org/wiki/Genotype

    Mendelian patterns of inheritance can be complicated by additional factors. Some diseases show incomplete penetrance, meaning not all individuals with the disease-causing allele develop signs or symptoms of the disease. [13] [15] [16] Penetrance can also be age-dependent, meaning signs or symptoms of disease are not visible until later in life.

  7. Classical genetics - Wikipedia

    en.wikipedia.org/wiki/Classical_genetics

    Classical genetics is the branch of genetics based solely on visible results of reproductive acts. It is the oldest discipline in the field of genetics, going back to the experiments on Mendelian inheritance by Gregor Mendel who made it possible to identify the basic mechanisms of heredity. Subsequently, these mechanisms have been studied and ...

  8. Mendelian randomization - Wikipedia

    en.wikipedia.org/wiki/Mendelian_randomization

    The Mendelian randomization method depends on two principles derived from the original work by Gregor Mendel on genetic inheritance. Its foundation come from Mendel’s laws namely 1) the law of segregation in which there is complete segregation of the two allelomorphs in equal number of germ-cells of a heterozygote and 2) separate pairs of allelomorphs segregate independently of one another ...

  9. Human genetics - Wikipedia

    en.wikipedia.org/wiki/Human_genetics

    Study of human genetics can answer questions about human nature, can help understand diseases and the development of effective treatment and help us to understand the genetics of human life. This article describes only basic features of human genetics; for the genetics of disorders please see: medical genetics.
