  2. Sperm cell replicates via meiosis

CROSSING OVER:

  • Crossing over is a unique process that occurs only during meiotic division. Crossing over, also called recombination, occurs during prophase I of meiosis.

  • Crossing over is the process by which non-sister chromatids of homologous chromosomes (a pair of similar but non-identical chromosomes from each parent).

  • Crossing over ensures genetic diversity in the gametes (daughter cells) produced from meiosis:

MEIOSIS:

  • Meiosis is the type of cellular division employed by sexual reproducing organisms to create sex cells or gametes.

  • Meiosis produces four genetically different daughter cells called gametes.

  • Sperm cells are gametes produced by male organism while egg cells are gametes produced by female organisms.
