Gene-edited pigs resistant to deadly PRRS virus

The transcript discusses the PRRS virus, which causes severe health issues in pigs, including breathing problems and stillbirths. Researchers at the University of Edinburgh have developed a gene-editing technique to remove a section of the pig CD163 receptor, which the PRRS virus uses to infect cells. Tests showed that gene-edited pigs did not contract the virus, and the genetic modification is permanent, allowing resistance to be passed down through breeding.

What was the outcome when gene-edited pigs were exposed to the PRRS virus?

How does the genetic edit affect the future generations of pigs?
