WebFeb 5, 2014 · To a first approximation cossing over events take place at random positions along the aligned chromosomes. Consequently the further two loci are apart, the more likely that there will be a crossing over event between them. Thus the recombination frequency can be used to measure the distance between two genetic loci (or genes). WebJul 19, 2024 · Good examples are the systems for integration of some bacteriophage, such as l, into a bacterial chromosome and the rearrangement of immunoglobulin genes in vertebrate animals.
