A Crispr calf was born at UC Davis
A Crispr calf named Cosmo was born in April at the University of California, Davis, after scientists spent years editing a sex-determining gene into bovine embryos, Wired reports. Alison Van Eenennaam, animal geneticist at UC Davis, pioneered the initiative to create a line of Crispr cattle tailored to the needs of the beef industry. In nature, there’s an equal chance that cows will give birth to male or female offspring. Van Eenennaam wanted to skew the odds in favor of producing an all-male herd, which has never been done before. More males, means bigger, beefier cattle, and more money.
