  2. Gene - Wikipedia

    en.wikipedia.org/wiki/Gene

    Each locus contains one allele of a gene; however, members of a population may have different alleles at the locus, each with a slightly different gene sequence. The majority of eukaryotic genes are stored on a set of large, linear chromosomes.

  3. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    As an example, in the LCA, one gene (gene A) may get duplicated to make a separate similar gene (gene B), those two genes will continue to get passed to subsequent generations. During speciation, one environment will favor a mutation in gene A (gene A1), producing a new species with genes A1 and B.

  4. Gene structure - Wikipedia

    en.wikipedia.org/wiki/Gene_structure

    Gene structure is the organisation of specialised sequence elements within a gene. Genes contain most of the information necessary for living cells to survive and reproduce. [ 1 ] [ 2 ] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.

  6. Introduction to genetics - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_genetics

    Humans have two copies of each of their genes, but each egg or sperm cell only gets one of those copies for each gene. An egg and sperm join to form a zygote with a complete set of genes. The resulting offspring has the same number of genes as their parents, but for any gene, one of their two copies comes from their father and one from their ...

  7. 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 ...

  8. Gene family - Wikipedia

    en.wikipedia.org/wiki/Gene_family

    Phylogenetic tree of the Mup gene family. A gene family is a set of several similar genes, formed by duplication of a single original gene, and generally with similar biochemical functions. One such family are the genes for human hemoglobin subunits; the ten genes are in two clusters on different chromosomes, called the α-globin and β-globin loci

  9. Overlapping gene - Wikipedia

    en.wikipedia.org/wiki/Overlapping_gene

    An overlapping gene (or OLG) [1] [2] is a gene whose expressible nucleotide sequence partially overlaps with the expressible nucleotide sequence of another gene. [3] In this way, a nucleotide sequence may make a contribution to the function of one or more gene products.
