A team of researchers has successfully reared an adult Mouse from
a single unfertilized egg, a scientific first, as reported by Margaret Osborne in a 2022 article for Smithsonian Magazine. The lab Rodent, who possessed only the mother’s genes, matured to adulthood and reproduced successfully, a feat which was previously thought to be impossible in Mammals, according to Alex Wilkins’ 2022 article for New Scientist.
