Unique chromosomes are formed, increasing genetic variation in species.

Crossing over (during prophase I of meiosis) exchanges DNA between homologous chromosomes, producing recombinant chromosomes and shuffling alleles. This increases genetic diversity among gametes and offspring, which fuels evolution and adaptation.
