Hornless offspring of a gene edited bull alongside a horned control cow. The reason cattle differ in their coat color, or whether or not they grow horns, is due to naturally occurring DNA sequence variations in their genome. These DNA sequence variations can also be introduced using gene editing as occurred with this black cow (#1) who inherited a gene-edited POLLED DNA sequence variant (PC allele) from her father, and as a result she is genetically hornless.
