Meet the first genetically modified bull. Why did scientists change it

Scientists at the University of California at Davis successfully produced a goby named Cosmo, which was genome-edited in embryonic phase so that it could produce more male offspring. The research was presented at a meeting of the American Society for Animal Science, according to the University of California, Davis.

Using CRISPR genome editing technology, researchers can purposefully make changes to the genome or insert useful genes. Scientists call such technologists. “Gene blow”. In this case, scientists have successfully introduced a bovine embryo, or the bovine SRY gene, which is responsible for the development of the male. This is the first demonstration of targeted gene insertion for large DNA sequences through embryo-mediated genome editing in cattle.
