  2. Human genetic variation - Wikipedia

    en.wikipedia.org/wiki/Human_genetic_variation

    Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population (alleles), a situation called polymorphism. No two humans are genetically identical. Even monozygotic twins (who develop from one zygote) have infrequent genetic differences due to mutations ...

  3. Human genetics - Wikipedia

    en.wikipedia.org/wiki/Human_genetics

    Human genetics. Human genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.

  4. List of genetic disorders - Wikipedia

    en.wikipedia.org/wiki/List_of_genetic_disorders

    The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.

  5. Mutation - Wikipedia

    en.wikipedia.org/wiki/Mutation

    Mutations can involve the duplication of large sections of DNA, usually through genetic recombination. [10] These duplications are a major source of raw material for evolving new genes, with tens to hundreds of genes duplicated in animal genomes every million years. [11] Most genes belong to larger gene families of shared ancestry, detectable ...

  6. Genetic variation - Wikipedia

    en.wikipedia.org/wiki/Genetic_variation

    Genetic variation is the difference in DNA among individuals [1] or the differences between populations among the same species. [2] The multiple sources of genetic variation include mutation and genetic recombination. [3] Mutations are the ultimate sources of genetic variation, but other mechanisms, such as genetic drift, contribute to it, as well.

  7. Mutation rate - Wikipedia

    en.wikipedia.org/wiki/Mutation_rate

    The human germline mutation rate is approximately 0.5×10 −9 per basepair per year. [ 1 ] In genetics, the mutation rate is the frequency of new mutations in a single gene, nucleotide sequence, or organism over time. [ 2 ] Mutation rates are not constant and are not limited to a single type of mutation; there are many different types of ...

  8. Chromosome abnormality - Wikipedia

    en.wikipedia.org/wiki/Chromosome_abnormality

    Chromosome abnormality. A chromosomal abnormality, chromosomal anomaly, chromosomal aberration, chromosomal mutation, or chromosomal disorder is a missing, extra, or irregular portion of chromosomal DNA. [1][2] These can occur in the form of numerical abnormalities, where there is an atypical number of chromosomes, or as structural ...

  9. Human mitochondrial genetics - Wikipedia

    en.wikipedia.org/wiki/Human_mitochondrial_genetics

    Human mitochondrial genetics is the study of the genetics of human mitochondrial DNA (the DNA contained in human mitochondria). The human mitochondrial genome is the entirety of hereditary information contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to ...
