NOTE on using the Synbreed package for some chapters

The synbreed package was archived on 02/2020. The reason for this was one of the major dependencies, the regress package is not available.  The synbreed package developers are working on an alternative. You may still be able to run synbreed on the R 3.5 version and manually download the synbreed package version 0.12-9.tar.gz from here:
