In meiosis, crossing over occurs, where homologous chromosomes synapse and their chromatids exchange genetic information. During crossing over, the allele for one trait swaps places with the allele for the same trait on the homologous chromosome. At this point, the sister chromatids are no longer identical. When the chromatids split from each other, there are four unique haploid sperm or egg cells.
