Final answer:

Crossing over during meiosis involves the exchange of genetic material between homologous chromosomes, creating unique combinations of alleles.


Explanation:

Crossing over during meiosis is represented by crossover events between homologous non-sister chromatids, resulting in a reciprocal exchange of DNA between maternal and paternal chromosomes. This process creates genetic variation as the recombinant sister chromatids carry a mix of genes from both parents, leading to unique combinations of alleles in offspring.
