genetic map
genetic mapn. A graphic representation of the arrangement of genes or DNA sequences on a chromosome. Also called gene map.genetic map n (Genetics) a graphic representation of the order of genes within chromosomes by means of detailed analysis of the DNA. See also chromosome map genetic mapping ngenet′ic map′
n. an arrangement of genes on a chromosome. genetic map or gene map A graphic representation of the arrangement of genes on a chromosome. A genetic map is used to locate and identify the gene or genes that determine a particular inherited trait. ♦ Locating and identifying genes in a genetic map is called genetic mapping.Thesaurus| Noun | 1. | genetic map - graphical representation of the arrangement of genes on a chromosomeorganization, arrangement, organisation, system - an organized structure for arranging or classifying; "he changed the arrangement of the topics"; "the facts were familiar but it was in the organization of them that he was original"; "he tried to understand their system of classification" |

genetic map[jə¦ned·ik ′map] (genetics) A graphic presentation of the linear arrangement of genes on a chromosome; gene positions are determined by percentages of recombination in linkage experiments. Also known as chromosome map. genetic map
genetic [jĕ-net´ik] 1. pertaining to reproduction or to birth or origin.2. inherited.genetic code the arrangement of nucleotides in the polynucleotide chain of a chromosome; it governs the transmission of genetic information to proteins, i.e., determines the sequence of amino acids in the polypeptide chain making up each protein synthesized by the cell. Genetic information is coded in DNA by means of four bases: two purines (adenine and guanine) and two pyrimidines (thymine and cystosine). Each adjacent sequence of three bases (a codon) determines the insertion of a specific amino acid. In RNA, uracil replaces thymine.genetic map 1. the location of mutations along the length of a chromosome, as determined by recombination experiments. The unit of length is the centimorgan (cM), one crossover per meiosis.2. the sequence of base pairs along the DNA of a chromosome, a technique being applied to humans. A gene map of Chromosome 18. From Copstead, 1996.genetic marker a gene having alleles that are all expressed in the phenotype, that is, they are codominant, and which can be used to study inheritance. The various blood group systems and serum or red blood cell proteins easily detected by electrophoresis or immunodiffusion are commonly used markers.ge·net·ic mapan abstract representation of the ordered array of genetic loci such that the interval between entries has algebraic signs and magnitude proportional to the expected number of crossings over between them and distances are algebraically additive; for example, on a genetic map the combined distance between locus A and locus C is the algebraic sum of the two distances between loci A and B, and B and C.genetic mapn.
