That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations. Nucleus transplantation experiments in mouse zygotes in the early 1980s confirmed that normal development requires the contribution of both the maternal and paternal genomes. The vast majority of mouse embryos derived from parthenogenesis (called parthenogenones, with two maternal or egg genomes) and WitrynaFor example, meerkats, which are found in Africa, are small carnivorous mammals that live underground. Meerkats stand tall on the ground, and when a predator such as a hawk approaches, one...
