Universidad de Yamanashi

Universidad de Yamanashi, specifically its Advanced Biotechnology Center, is a Japanese university known for its research in biotechnology. Recently, the university, led by researcher Teruhiko Wakayama, has gained attention for a 20-year study investigating the limits of mammalian cloning. The research involved cloning mice for 58 generations, creating over 1,200 individuals. The study revealed that repeated cloning leads to accumulating mutations and a decline in viability after approximately 25 generations, eventually becoming incompatible with life. This research is significant because it demonstrates the finite nature of cloning and highlights the importance of sexual reproduction for maintaining genetic diversity and long-term survival in mammals. The findings contribute to a deeper understanding of the biological constraints of cloning and its potential limitations.
