    Sainmhíniú "tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction as an exception to Mendel's Law of Independent Assortment" Tagairt "COM-Terminology Coordination, based on: 'Genetic linkage' (14.4.2021)"
    Nóta "Genetic linkage is often defined, from a molecular viewpoint, as the tendency of alleles carried by the same DNA molecule to be inherited together. However, if two genes are very far apart on a very long DNA molecule, linkage may not be observed in practice. In this example, consider a long chromosome, carrying all five genes, A, B, C, D, and E. It can be observed that A is linked to B and C, and that C and D are linked to E, but that no linkage is observed between A and E (Fig. 2.24). Given that A is on the same DNA molecule as B and that B is on the same DNA molecule as C, etc., it can be deduced that A, B, C, D, and E must all be on the same chromosome. In genetic terminology, it is said that A, B, C, D, and E are all in the same linkage group. Even though the most distant members of a linkage group may not directly show linkage to each other, their relationship can be deduced from their mutual linkage to intervening genes."

    Sainmhíniú map showing the linear order of the genes along a chromosome with distance proportional to the frequency of recombination Tagairt "Kim Hughes. Genetics and Evolution. 5 GENETIC LINKAGE AND MAPPING. School of Integrative Biology. Dept. of Animal Biology. University of Illinois at Urbana-Champaign, http://www.life.illinois.edu/ib/201/lectures/Mapping.pdf [31.10.2014]"
    Nóta "Unit of distance in linkage map is a map unit--1 map unit is equal to 1 percent recombination or centimorgan1. A map unit is also equivalent to the physical distance along a chromosome which will experience 1 crossover event in every 50 meiotic divisions (1 crossover in 50 meiotic divisions = 2 recombinant gametes in every 200 = 1 % recombination). So two genes that recombine with a frequency of 1% are said to be 1 map unit apart.1 centimorgan [ IATE:1106821 ]"
