  2. Heredity - Wikipedia

    en.wikipedia.org/wiki/Heredity

    Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

  3. Genetics - Wikipedia

    en.wikipedia.org/wiki/Genetics

    Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1 ] [ 2 ] [ 3 ] It is an important branch in biology because heredity is vital to organisms' evolution . Gregor Mendel , a Moravian Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically.

  4. Human genetics - Wikipedia

    en.wikipedia.org/wiki/Human_genetics

    Population genetics is the branch of evolutionary biology responsible for investigating processes that cause changes in allele and genotype frequencies in populations based upon Mendelian inheritance. [3] Four different forces can influence the frequencies: natural selection, mutation, gene flow (migration), and genetic drift. A population can ...

  5. Heritability - Wikipedia

    en.wikipedia.org/wiki/Heritability

    Heritability can be univariate – examining a single trait – or multivariate – examining the genetic and environmental associations between multiple traits at once. This allows a test of the genetic overlap between different phenotypes: for instance hair color and eye color. Environment and genetics may also interact, and heritability ...

  6. Outline of genetics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_genetics

    The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...

  7. Introduction to genetics - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_genetics

    Genetic disorders are diseases that are caused by a single allele of a gene and are inherited in families. These include Huntington's disease , cystic fibrosis or Duchenne muscular dystrophy . Cystic fibrosis, for example, is caused by mutations in a single gene called CFTR and is inherited as a recessive trait.

  8. Gene - Wikipedia

    en.wikipedia.org/wiki/Gene

    In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity.The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA.

  9. History of genetics - Wikipedia

    en.wikipedia.org/wiki/History_of_genetics

    Darwin's own theory of heredity, pangenesis, did not meet with any large degree of acceptance. [14] [15] A more mathematical version of pangenesis, one which dropped much of Darwin's Lamarckian holdovers, was developed as the "biometrical" school of heredity by Darwin's cousin, Francis Galton.
