"Unique chromosomes are formed, increasing genetic variation in species."

Explanation: Crossing over exchanges DNA between homologous chromosomes during prophase I of meiosis, producing recombinant chromosomes and new allele combinations. It promotes genetic diversity. (The other choices are incorrect: DNA replication happens before meiosis, identical offspring result from asexual reproduction, and growth/healing are mainly functions of mitosis.)
