This process is crucial to human development. Carlos and Pereira suggest that deletion of several genes functionally comparable to those that allowed the creation of viable bi-maternal offspring in a mouse model could allow a human egg\u00a0 to compensate for the absence of a paternally imprinted set of chromosomes, meaning it would be able to express proper alleles only using maternal DNA. Achieving diploidy and heterozygosity may be possible with the use of a bacterium, Carlia and Pereira hypothesize. The bacterium <\/span><i><span style=\"font-weight: 400\">Wolbachia sp.<\/span><\/i><span style=\"font-weight: 400\"> can live symbiotically within a cell and is capable of inducing parthenogenesis in mites\u2013parthenogenesis is advantageous to the bacterium, as it allows it to be transmitted to the host\u2019s offspring (sounds wild, I know). Finally, the properly diploid, heterozygous gamete must be able to function as a zygote. In mice, the precise mutation of a proto-oncogene (a gene allowing for regular cell growth that, upon mutation, may induce cancer) can cause parthenogenetic activation, so it is proposed that the mutation of a similar gene in humans may do the same. In combination, these techniques would theoretically allow for viable human parthenogenetic offspring. <\/span><\/p>\n<p><span style=\"font-weight: 400\">Putting these techniques into practice today would, of course, be considered unethical. However, the advent of \u201cdesigner babies\u201d and other uses of genetic engineering to ensure health and longevity suggest that genetic alteration for the purposes of parthenogenesis may not be an impossibility in the next hundred years, especially due to the so-called \u201cmale fertility crisis.\u201d Who knows, maybe Beyonc\u00e9\u2019s \u201cRun the World (Girls)\u201d was prophetic \ud83d\ude42<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Joanna Russ\u2019s short story \u201cWhen it Changed\u201d got me thinking: with the right science, would human parthenogenesis be possible?
