Correct Answer: Option C

Explanation

During prophase I, homologous chromosomes from each parent pair up and exchange genetic material, a process known as crossing over. This process creates new combinations of genes in the resulting gametes. When two gametes unite during fertilization, the offspring will have a unique combination of DNA.

Genetic recombination during fertilization takes place in the prophase I stage of meiosis ( part labelled III)
