WebJan 24, 2024 · Crossing Over. Linkage is the tendency to keep the genes together over several generations. Crossing over leads to the separation of linked genes by the exchange of genes between non-sister chromatids of a homologous pair of chromosomes. It involves a single chromosome. It involves a pair of homologous chromosomes. Webtwo unlinked genes. Recombination results when crossing over during meiosis separates linked genes Reciprocal exchanges between homologous chromosomes are the physical basis of recombination. We will cover the actual mechanism of recombination in another lecture. Using chromosomes that had cytologically visible abnormalities, Creighton and ... There are two popular and overlapping theories that explain the origins of crossing-over, coming from the different theories on the origin of meiosis. The first theory rests upon the idea that meiosis evolved as another method of DNA repair, and thus crossing-over is a novel way to replace possibly damaged sections of DNA. The second theory comes from the idea that meiosis evolved from bacterial transformation, with the function of propagating diversity. In 1931, Barbara McClin… black ice car
