Are there hornless bulls?

In 2016, scientists reported that two male dairy bulls had been born with a hornless mutation that had been introduced into their DNA sequence using genome editing

Unnatural Selection (or stylized as, "unnatural selection") is a 2019 TV documentary series that presents an overview of genetic engineering and particularly, the DNA-editing technology of CRISPR, from the perspective of scientists, corporations and biohackers working from their home.
