Mapping hot swap spots Scientists who have built a detailed map of sites where genetic information is swapped between parental chromosomes have provided insights into how these sites influence human genome evolution and genetic disease. To form sperm and eggs, our diploid cells -- each containing two copies of our DNA -- undergo a special cell division that halves the DNA content. This division, meiosis, involves the exchange of genetic information between parental chromosomes by a process called recombination. Going forward, the maps they created could be used for a variety of purposes, including studying the causes of genomic disorders. scim.ag/1ugfzEb ($)
