CRISPR Creates Mice with Two Dads

Chinese scientists have used CRISPR to create mice with two fathers that survive to adulthood. By editing 20 imprinted genes, they bypassed the developmental abnormalities usually seen in bi-paternal mice. This research offers insights into genomic imprinting and potential reproductive technologies, but highlights significant ethical and safety concerns regarding human applications.
