DNA Is Constantly Changing through the Process of Recombination

WebCrossing over is the swapping of chromosomal segments between homologous chromosomes that came from different parents. This event occurs mostly during prophase I of meiosis, when homologous chromosomes (one being the paternal homolog and the … WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells.
