That’s not true: xnu has significant parts originally copied from the FreeBSD kernel, alongside the Mach parts and the IOKit parts. However, considering not just the changes made in the process but also the ~20 years of independent evolution since then, I wouldn’t count on anything from the modern FreeBSD kernel being easy to port. Probably easier to start from scratch.
