WebJan 9, 2024 · During meiosis of the cells, DNA recombination can occur naturally by the process called crossing over between homologous chromosomes. Crossing over is an exchange of genetic material … WebThe process of crossing over was used in genetic mapping to understand the order of genes on a chromosome, and to determine the distance between them. This works on the basis that if two genes are present far apart on the chromosome, the frequency of crossing over between the two will be greater. All individuals produce beings similar to ...
