In meiosis, this is called homologous recombination, the molecular event that shuffles parental genomes and produces the genetic diversity every species depends on. Worn as a ring, it sits as a quiet reference to that crossover moment. The Science Behind Crossed DNA When chromosomes recombine during meiosis, DNA strands from
