Are you having trouble creating the pedigrees taxonomy?
If so, you can create it manually using code in the theme’s functions.php file: http://www.smashingmagazine.com/2012/01/04/create-custom-taxonomies-wordpress/
Or use a plugin like Custom Post Type UI: https://wordpress.org/plugins/custom-post-type-ui/
I use the second method as it allows me to quickly create taxonomies and link them to posts, custom post types or both.
