What is crossover definition?

Crossover is a term associated with genetics, particularly regarding inheritance and genetic variation. It refers to the exchange of genetic material between homologous chromosomes during meiosis that results in new combinations of alleles (different versions of genes) in offspring. This process contributes to the genetic diversity and variability of populations, as well as evolution. Crossover can occur between non-sister chromatids within a bivalent of a paired chromosome, a process called homologous recombination. This genetic exchange helps in increasing genetic variation, which is the fuel for evolution and adaptation. Additionally, crossover can also be used in the context of music, where it refers to the process of mixing elements from different genres or styles to create a new sound aesthetic.
