Individual members of the same species are genetically very different because of a process called meiosis which creates gametes. During the meiosis (prophase I) the process called crossing over occurs. Crossing-over represents the exchange of genetic material between non-sister chromatids of homologous chromosomes which results in new combinations of genes on each chromosome (genetic variation).
