Ordinarily, gametes produced by separate individuals unite by a process of fertilization to form a diploid <a href="/wiki/Zygote" title="Zygote">zygote</a> that can then develop into a genetically unique individual progeny. However, some animals are also capable, as an alternative reproductive process, to reproduce parthenogenetically. Parthenogenesis has been described in snakes and lizards (see Wikipedia <a href="/wiki/Parthenogenesis_in_squamates" title="Parthenogenesis in squamates">Parthenogenesis in squamates</a>), in amphibians (see Wikipedia <a href="/wiki/Parthenogenesis_in_amphibians" title="Parthenogenesis in amphibians">Parthenogenesis in amphibians</a>) and in numerous other species (see Wikipedia <a href="/wiki/Parthenogenesis" title="Parthenogenesis">Parthenogenesis</a>). Generally, meiosis in parthanogenetically reproducing animals occurs by a similar process to that in sexually reproducing animals, but the diploid zygote nucleus is generated by the union of two haploid genomes from the same individual rather than from different individuals. </p> <div class="mw-heading mw-heading2"><h2 id="See_also">See also</h2><span class="mw-editsection"><span
