Chromosomal crossover

Chromosomal crossover is a natural process during cell division where pairs of chromosomes exchange segments of genetic material. This swapping occurs at specific points called chiasmata, resulting in new combinations of genes. It increases genetic diversity within a species by reshuffling inherited traits from parents, which is important for evolution and adaptation. Essentially, crossover creates new genetic variations by mixing parts of chromosomes, contributing to the unique genetic makeup of offspring.
