Chromosomal recombination is a biological process that occurs during meiosis, where genetic material is exchanged between homologous chromosomes. This exchange leads to new combinations of genes, contributing to genetic diversity in offspring. It is essential for evolution and adaptation in populations. During recombination, segments of DNA are broken and rejoined, creating variations in the genetic code. This process can occur through mechanisms such as crossing over, where sections of chromosomes physically swap places. The result is a mix of traits from both parents, which can enhance survival and reproduction in changing environments.
